The Advanced Power Systems (APS) Research Center explores alternative energy sources that help mitigate the economic ramifications of increased oil prices.
The focus is on alternative energy sources, such as biofuels, fuel cells, and wind turbines.
The most immediately feasible alternative energy source is biofuels. With decades of expertise and numerous innovative engine research labs, the APS group is well equipped to devise the necessary modifications to internal combustion engines that will allow them to run on high mix biofuel, improving efficiency and reducing emissions without sacrificing torque, fuel economy, or smooth vehicle operation.
Tomorrow Needs Sustainable Fuels
This group also focuses on energy system optimization to ensure efficient use of future fuel supplies.
Thermal-fluid experts are working to characterize two-phase flows in heat exchangers, enhance flows in fuel cells, and develop methods and technologies that will allow the utilization of gasified natural material in power generation systems. Researchers are also investigating ways to optimize the flow of air across wind turbines in order to increase productivity. By investigating current and emerging technologies, the group is bridging the gap between today's fossil fuel economy and a multisource economy that promises a more stable and sustainable future.

Summary for Public Release
Michigan Technological University in partnership with General Motors will develop, validate and demonstrate on a fleet of eight model year 2016 Chevrolet Volts and a mobile connected cloud computing center, a model based vehicle and powertrain controller. The selected vehicle, the MY16 Volt contains a unique powertrain architecture and enables five distinct operating modes including all electric (EV), plug-in-electric hybrid (PHEV), and hybrid electric vehicles (HEV). The model based controller will encompass a full real-time physics based coupled powertrain vehicle dynamics model leveraging vehicle conductivity with vehicle-to-vehicle and infrastructure to vehicle communications with real-time traffic modeling and predictive speed horizons and eco-routing. The goal is to achieve at least a 20% reduction in energy consumption (electrical + fuel) and a 6% increase in electric range through the first ever implementation and connection of route planning, powertrain energy management model predictive controller algorithms. Connectivity data from other vehicles, infrastructure, GPS, traffic, and desired route planning combined with a physical model of the powertrain-vehicle system allows prediction of the vehicle’s future speed and enables forward looking powertrain mode selection and reduction of the energy utilization from the battery and fuel.

Rapid Screening with Paddle Fast Pyrolysis Systems
Investigators | |
---|---|
Principal Investigator: Ezra Bar-Ziv | |
College/School: | College of Engineering |
Department(s): | Mechanical and Aerospace Engineering |
Pyrolysis is the thermochemical breakdown of organic matter into oil and gas products in inert atmosphere in the temperature range 350 to 600 °Celsius. Ensuring that the heating rate of the organic matter is faster than approximately 100 Celsius/sec (i.e. fast pyrolysis) ensures that the yield of product bio-oil is maximized. Through the process of fast pyrolysis, followed by bio-oil upgrading woody and herbaceous organic matter can be converted to liquid transportation fuels, including gasoline, diesel and jet fuel.
This project consists of two primary tasks. The first task will design, manufacture, test and operate two lab-scale paddle fast pyrolysis systems for rapid evaluation of biomass sample performance in fast pyrolysis conversion to bio-oil. Tests of several materials (minimum of 10) will be conducted to demonstrate operation of the reactors. The second task will develop a preliminary reaction model that predicts the loss of carbon, hydrogen, and oxygen (CHO) molecules from the solid feedstock for the experiments.
This project is a collaboration of the Idaho National Laboratory (INL) and Michigan Technological University (MTU). INL will provide the biomass feedstocks for the fast pyrolysis experiments and will also be responsible for chemical characterization of the feedstocks. MTU will first design and fabricate a small prototype paddle fast pyrolysis reactor capable of processing a minimum of 50 mg of material per minute. MTU will conduct preliminary tests using the small prototype reactor and will use the data to design and fabricate a second reactor that is capable of processing a minimum of 200 mg of material per minute. Preliminary tests using both reactors will determine whether the design concept is scalable. In this project, MTU will be responsible for conducting fast pyrolysis tests using the test reactors and for developing the preliminary predictive reaction models. MTU will retain ownership of one of the fast pyrolysis reactors and will deliver the other reactor to INL. If the reactor design and associated reaction model are successful, future work outside of the current project may design and fabricate a third reactor capable of processing l kg of material per hour (16,667 mg/min).
Task 1: Design and fabricate a small prototype paddle fast pyrolysis reactor. Use the prototype reactor to conduct preliminary experiments on select feedstocks.
Task 2: Design and fabricate a second paddle fast pyrolysis reactor. The second reactor shall be capable of processing a minimum of 200 mg of material per minute.
Task3: Conduct validation tests with either reactor using a minimum of ten feedstocks. Each feedstock will be tested a minimum of four times to estimate repeatability. For the tests, INL will provide a minimum of 20 kg of each feedstock, which will be divided into a minimum of six consistent specimens. Solid and liquid products from each test will be delivered to INL for analysis. INL will analyze the solid products for CHON and total mineral content and the liquid products for CHON, water, and TAN. The liquid product may also be analyzed for sulfur, density, viscosity, pH, and product distribution using GC-MS or GC-FID. INL will characterize the raw feedstocks for elemental composition (CHONS), carbohydrate/fiber analysis (cellulose, hemicellulose, and lignin), mineral content, and heating value. INL will provide instructions for sample storage and transport for analytical analysis.
Task 4: Develop a preliminary reaction model that predicts the loss of carbon, hydrogen, and oxygen (CHO) molecules from the solid feedstock for the experiments. In addition, the preliminary reaction model will predict the fate of these removed organic compounds as partitioned in the remaining solid char, in either the primary non-condensable gas (CO and C02) and primary condensable species (pyrolysis oil and water). No secondary reactions will be interpreted in the preliminary model. The reaction model will be able to include up to three stages at potentially different operating conditions to resolve the mass losses as the fast pyrolysis reaction progresses from mild to severe conditions. These three stages can potentially produce three distinct gas/vapor species, that in-tum could be targeted for fuel/chemical production or conversion.
Task 5: Deliver a paddle fast pyrolysis reactor systems to INL that meets the features described in Task 1.Awarded Amount: $99,995

GOALI: Collaborative Research: Easily Verifiable Controller Design

Principal Investigator: Mahdi Shahbakhti | |
College/School: | College of Engineering |
Department(s): | Mechanical and Aerospace Engineering |
Overview:
Verification and Validation (V&V) of controller designs for complex dynamic systems is currently too costly and time consuming. The V&V process for a typical modem automotive electronic control unit can take about two man-years, and it can easily cost 5-6 million dollars. A large number of errors detected during independent V&V are errors that are introduced during the initial stages of controller development. V&V would cost 10 times less if those errors could be identified and fixed during the early stages of controller software design. Reducing cost and time of V&V is a major challenge for all complex control systems - a challenge that will be addressed in this project.
A critical gap occurs when uncertainty in controller software/hardware implementation is not considered as part of the controller design. This gap leads to the need for many V&V iterations and results in costly controller design. This project intends to fill this gap by (i) modeling and quantification of uncertainty that arises from controller implementation imprecisions, (ii) design of robust controllers to overcome implementation uncertainty, and (iii) development of an adaptive control framework to update uncertainty bounds from implementation imprecisions.
The outcome of this project will be a novel, easily verifiable controller design that can minimize V& V iterations for complex industrial control systems, thereby reducing cost. The control framework will be generic, and it will be applicable to a wide range of nonlinear control systems.
This multi-disciplinary research will be carried by scholars from UC Berkeley and Michigan
Tech. Toyota Motor Company will be the industrial partner for this project. The project will broadly reach industry and K-12 students through outreach activities that will be designed and implemented.
Intellectual Merit:
There are three main areas of intellectual merit for this project. The first area is filling the gap between control engineering and software/hardware engineering disciplines for improved controller design. The second area is the development of a novel generic control theory for easily verifiable controllers that can be widely applied to complex industrial control systems.
The third area is the development of control-oriented uncertainty models to characterize the implementation imprecision for industrial controllers, particularly for quantization and fixed-point arithmetic imprecisions. The overall expected outcome from these three main contributions will be an uncertainty-adaptive, easily verifiable control theory framework that industry can adapt to controller design processes to minimize the time and cost of controller development.

OVERVIEW
Evaluate, and develop the durability and performance of E3 spark plugs when installed in a Natural Gas fueled application. To keep costs low, and lead times short, a Natural Gas fueled generator set is used as the testbed for this work. Work with E3 to develop additional testing programs on other specific engines, such as large truck engines and / or evaluate the combustion performance of the spark plug in Natural Gas applications.
EXPERIMENTATION PLAN
The testbed for this durability testing is a 30 kW Natural Gas fueled generator set. The genset is powered by a 4-cylinder GM engine. The engine is turbocharged, and therefore is capable of achieving a high specific load. The 4-cylinder engine allows for one or two baseline spark plugs and two or three spark plugs under test to be evaluated. As the objective of the testing is durability, the test bed is lightly instrumented providing only the most critical parameters needed for spark plug durability evaluation and / or engine control. Engine load is varied in two or three steps, with approximately equal time spent in each step over the course of the testing. One of the steps is 100% load. The other loads include a mid-load and / or a low-load. The speed is the generator required speed of 1800 RPM. After approximately every 50 hours of operation all spark plugs are removed and their gap measured, and their visual condition noted. After approximately every 100 hours of operation the spark plugs also have photographs recorded, the mass of the spark plug recorded, and the electrical resistance of the core, and the resistance to the shell recorded. Additionally every 100 hours intermediate test results including data recorded on the spark plug itself (gap, resistance, mass, etc.) as well as engine data (EGT, load profile, etc.} sent to E3. After approximately every 350 hours of operation the engine undergoes maintenance including oil and filter changes, and new ignition components (distributor cap, rotor, and spark plug wires) to ensure all spark plugs are receiving a high quality "signal" throughout the testing. At this time the compression and leakdown rate of the engine is also measured to ensure the engine remains mechanically sound and / or all cylinders are approximately equal.

A group of researchers at Michigan Tech and REL propose to design, develop, integrate, and test a CNG tank that will have a conformable shape for efficient storage in a light-duty pick-up truck. Michigan Tech is well known for its research in automotive technology, design optimization via simulation, and aluminum material research. REL is the leader in design and manufacturing of aluminum conformable pressure tanks.
This research will be conducted in two phases. Phase 1 (1 year) will be a proof-of concept phase in which existing technology will be used to fabricate, integrate, and test a conformable tank for a light-duty truck using existing materials technology and fabrication techniques. In Phase 1, the materials development effort will initiate.
The Phase 1 tank is a simple rectangular box geometry to demonstrate capability of non-cylindrical shapes. The end of Phase 2 (2 years) will result in a conformable tank with an optimized internal structure and improved lightweight material for greater efficiency, capacity and durability. The optimized tank will be integrated and tested on a light-duty pick-up truck that has been converted for CNG.

MTU Consortium in Diesel Engine Aftertreatment Research
Starting from a well-established research program and as a result of a Dept. of Energy 3 year project, we have significantly enhanced our laboratory, experimental methods and procedures, and modeling/estimator capability. The faculty and students have produced thirteen publications from this research.
Consortium Goal:
The underling goal of the consortium is to develop and conduct precompetitive research on advanced aftertreatment systems through experimental engine methods, development and calibration of high fidelity models, and development and application of estimators and controllers. Achieving this goal will provide an improved understanding of the systems under dynamic and low temperature conditions characteristic of advanced medium and heavy duty diesel engines allowing the consortium members to apply this knowledge and models to improve system performance, reduce cost, and develop new approaches to diagnostics and increase robustness of their on-board-diagnostics.
Research Activities:
The existing facilities and an extensive model base will be used as developed in previous research including the current DOE program. This includes temperature controlled exhaust, positive torque drive cycles, and validated component models and estimators. Additionally we will add real-time functionality to perform aftertreatment estimation and control in the engine test cell.
The consortium research themes integrate fundamental and applied aspects of (1) Experimental Engine Studies (2) Modeling and Simulation and (3) Estimation, Control, and diagnostics. The proposed research is split into three major themes (I) Experimental, (II) Modeling, and (III) Estimation and Controls with a number of outcomes from the composite research program.
Areas of study will be determined based upon proposed research by MTU with input from the Partners to direct the research.
Based upon input from our partners and continuing some efforts from the DOE program, the following have been identified as key areas from which yearly research topics will be selected.
- Experimentally validated reduced order models and state estimation algorithms of aftertreatment components which are accurate for low temperature and dynamic operation.
- Quantify particulate matter (PM) maldistribution, loading, and NO2/PM ratio effects on passive and active regeneration, bio-fuel blends, and aging for catalyzed particulate filters (CPFs).
- Increased knowledge of ammonia (NH3) storage behavior, optimal NH3 loading, hydrocarbon (HC) poisoning, and aging for selective catalytic reduction (SCR) catalysts
- Understanding effect of sensor type/configuration on state estimation quality.
- Optimal reductant strategies for SCR operation and CPF regeneration.
- Integrated response and optimization of engine feedgas and aftertreatment systems
- Thermal control of the aftertreatment components for light-off, maintaining operational temperature, and regeneration relevant to engine low temperature operation and integration with exhaust energy recovery systems
- Fundamental studies of DEF introduction and functional responses – hydrolysis and pyrolysis
- Diagnostic concept development: Based upon existing virtual sensor and estimator work this will be translated into system and component diagnostics
- Sensor displacement by applying estimators and virtual sensors. For example, determining whether a NH3 sensor is needed if an accurate SCR NH3 storage model is available.
- Improved DPF PM estimation and measurement. Although systems are going to increase passive oxidation with engines moving to higher NOX and lower PM, this is still an important research area to improve methods to accurately estimate CPF loading.
- Alternative and integrated aftertreatment technologies such as integrated SCR with PM filtration. Many fundamental questions remain about this technology including architecture of combining functions that still enable high passive PM oxidation and high NOX conversion.
- PM Sampling and related diagnostic use. Quantifying the effect of sensor location on the ability to detect failures. does it matter where the sensor is and what the type of failure is. e.g. For example, how does the location of the PM sensor impact the speed of CPF melt down detection and can this speed of detection be optimized?

This continues work from the Ford DOE Program1 on "Advanced Gasoline Turbocharged Direct Injection (GTDI) Engine Development," for which Michigan Tech was subcontracted to conduct. The following is the proposed SOW for continuation of the ignition research areas with additional studies in an optical engine.
The proposed work is broken into the three components, (1) combustion lab, (2) metal engine, and (3) optical engine studies. The advantage of this workflow is that details on the Ignition system can be synergistically studied at multiple stages with specific instrumentation to determine the underlining principles behind the drivers for ignition system requirements and performance under highly stressed operation resulting from lean/dilute operation with in-cylinder flow.
1. Combustion Laboratory
Studies in the Combustion lab in the combustion vessel build on work conducted during the DOE program. In this work isolated ignition events can be studied in detail under controlled thermodynamic and flow conditions. The combustion lab is instrumented with a Ford provided Variable Output Ignition System (VOIS) capable of driving four coils with variable dwell, phasing, and quenching to a single spark-plug. The combustion vessel is highly configurable with instrument ports and window ports. The combustion vessel can be setup and arranged to cover a wide array of optical studies under conditions representative of in-cylinder conditions. The thermodynamic conditions are generated by controlling the fuel mixture composition and stoichiometry through mixing individual gases (fuel, 0 21 N21 C021 etc.), pressure, and temperature.
The flow conditions are set by using a shrouded fan system. By changing the fan configuration, fans' speed and shroud, the flow past the spark plug electrode can be controlled. As a result the ignition (break-down, arc and glow discharge) and initial flame kernel development can be studied with high speed imaging and other diagnostics. The proposed work is to conduct 200 tests in which the conditions will be determined by direction of Ford technical staff in consultation with Michigan Tech. These tests are broken up into multiple stages.
2. Metal Engine
The metal engine work continues on the V6 3.SL IVCT engine that is setup for testing at Michigan Tech in a dynamometer engine test cell. It has the Ford PCM with ability to integrate prototype code via ATI no-hooks, a prototype EGR system controlled by a prototyping ECU, the Ford Variable Output Ignition System (VOIS) for dual coil per cylinder control, and instrumentation including cylinder pressure transducers coupled with a combustion analysis tool. Additionally a high speed 10M samples per second, long record length, National Instrument system has been incorporated for measurement of ignition system secondary characterization. This coupled with the cylinder pressure combustion analysis tool provides characterization of ignition system performance with combustion metrics including combustion phasing, combustion durations (0-10, 10-90% mass faction bum, combustion variability through coefficient of variance (COV) and lowest net value (LNV) of IMEP and percent misfires. In-cylinder flow motion can be set to low or high by inserting tumble planks in the intake ports.
The Ford VIOS system drives two coils per cylinder and when used with variable duration (short, medium, long, and extra-long) coils with controlled dwells can provide a wide range of ignition energy profiles including continuous and discontinuous discharges with variable delays and individual durations. The system drives all 6 cylinders with secondary measurements on cylinder 1. Additionally quenching has been added to truncate the tail of the glow discharge for additional energy-phasing-duration control for cylinder 1. Supplemental measurements of secondary voltage and current are measured in the DAQ systems.
Standard tests include:
- EGR and lean sweeps at constant speed I load to identify dilution limits as a function of coil energy and discharge duration
- Dwell sweeps with varying coils
- Coil 8 delay sweeps where the interval between the first coil (A) and second call discharges is changed
- Restrike and quenching with variable energy and delay
3. Optical Engine
Michigan Tech has been working with Mahle Powertrain (MPT) on the development and integration of an optical engine for research at Michigan Tech for research purposes. To develop the setup and controls for the engine, MTU has setup a 2013 2.0L EcoBoost metal engine. Finalization of the development on the metal engine was completed in December of 2013. The engine is setup with standard DI side mount injection and single coil ignition. The engine controls are done via a rapid prototyping controller. As part of this work MTU will develop controls for a dual coil ignition system for the engine. The system will perform individual control for the dwell and phasing of the two coils with a diode pack similar to the Ford VIOS to drive to a single spark plug. Ford will provide necessary coils and plugs for study. Optionally MTU will setup for N2/C02 gas dilution as a surrogate for external EGR.
The proposed work is to conduct 4 weeks of testing once the engine setup is complete starting in April. The tests will be broken up into 4 phases each 1 week in duration. The test conditions will be determined by direction of Ford technical staff in consultation with Michigan Tech.

Ford Diesel Spray Studies: Rate of Injection Measurement Phase 2
Overview:
To supplement the acquired rate of injection (ROI) data from the initial momentum flux measurements, additional tests will be undertaken to characterize the initial transient rate of injection spray development. This will include investigating the effect of impingement distance on the transient rate of injection, accomplished through the use of differing anvil lengths. Tests will be conducting using the standard Baseline B multi-hole Injector. An option to look at the hole to hole variations in transient ROI development and to correlate this to the Bosch ROI is included along with other testing and analysis options.
Objectives
Utilizing the impingement momentum flux method for ROI, determine the following:
Characterize the influence of impingement distance on the measured transient rate of injection by measuring at 4 distances (nozzle exit to anvil).
Options are included for the following:
- Characterize the plume to plume differences at early injection and compare to the Bosch ROI by appropriately phasing and summing the individual nozzle impingement ROI measurements.
- Model the impact of ROI distance using the momentum flux model of Naber and Siebers (1) extended to transient spray momentum flux by Musculus and Kattke (2)
- Image the impingement with high speed micro-photography. Imaging will be acquired of the first impingement only, through the Plexiglass viewing port on the ROI fixture.
This work will utilize the developed ROI fixture from Phase 1 testing and the existing DAQ system, but will require hardware modifications in the form of different anvils. Included would be characterization at different injection pressures and impingement distances.

Enhancement of Corn-based Fuel for Recreational Engines and Vehicles

Principal Investigator: Scott Miers | |

Department(s): | Mechanical and Aerospace Engineering |
Project Relevance
The Renewable Fuel Standard within the Energy Independence and Security Act of 2007 sets the required quantities of renewable fuels required in the marketplace, over a 14-year period. In order to meet the renewable fuel requirement of 2012, the ethanol content in gasoline increased above 10%.
E15 is slowly replacing E10 at fuel stations, which means snowmobiles and other recreational vehicles will be required to operate on a fuel that they have not been calibrated for. While a majority of current research projects focus on automotive applications of renewable fuels, little work to date has focused on recreational power sports applications. The effects of renewable fuels on open-loop systems, such as those on most recreational vehicles, are highly unknown and thus produce concern on the part of owners and manufacturers.
The state of Minnesota has over 250,000 registered snowmobiles, the highest number in the United States. However, E15 is not currently approved for use in these vehicles due to detrimental impacts and limited test data. A recent study conducted by Michigan Technological University and funded by the Department of Energy, found that E15 fuel in snowmobiles caused increased exhaust system temperature and NOx emissions, reduced carbon monoxide and 1,3 butadiene emissions, degraded cold-start performance, and increased fuel consumption. The engine calibrations were not modified for E15, and thus the data represents the situation of misfuelling a snowmobile with E15.
The goal of this project is to determine the required calibration changes to minimize the negative impacts from higher oxygen concentration fuel while also taking advantage of improved fuel properties to increase fuel economy, reduce emissions, and improve performance. In addition, evaluating what sensors are required to implement the calibration changes in a real-time manner will be assessed. This data ultimately improves the recreational manufacturer's acceptance of these new fuels, because they understand the required changes necessary to successfully implement the fuels.
Benefit of the Project to Minnesota Corn Farmers
Creating a high demand for corn products is important for Minnesota farmers. E15 fuel has increased the demand for corn-based fuel but it is not approved for use in recreational engines and vehicles. To maximize the demand for higher alcohol content fuel, all vehicles must be legally allowed to use it. This project provides real-world data that recreational engine and vehicle manufacturers can use to determine the impact of higher oxygen concentration fuel on their products and thus implement the necessary changes to take advantage of the new fuel properties. Exploiting the benefits of ethanol blended fuels helps offset the reduction in fuel economy and increased exhaust temperature. This in turn improves the acceptance of these new blends and ultimately the demand for corn-based fuel.

OVERVIEW
Following a project to evaluate the AUTOEKG FSA8 on four vehicles "Diagnosing Induction System Degradation and Evaluation of Remedial Chemicals in Automotive Engines," it has been mutually determined by ITW and Michigan Tech that additional testing should take place. The additional testing will be done on a population of 30 vehicles, but will not include the extensive tests and measurements taken during the first study.
The population of 30 vehicles will allow for more statistically significant results. The study will be advertised in a Michigan Tech newsletter to find willing participants. Participants will be incentivized with a pre-paid gift card. The volunteered vehicles will first be examined by the research team to ensure the vehicles meet the requirements of the project. After choosing 30 suitable vehicles, each vehicle will be scheduled for an appointment at the Advanced Power Systems Research Center. During this appointment each of the vehicles will have borescope images taken of at least 1 intake valve, and have EKGFSA scores recorded. A portion of the vehicles will have their fuel systems cleaned using ITW chemical products, while a portion will remain as a control group. The owners will be instructed to consume 1 tank of fuel, then bring their vehicle back In for a follow-up appointment, where once again EKGFSA scores will be recorded and borescope images collected. Following this work, results will be summarized and presented to ITW in a web conference. A written report will also be issued.

Introduction
Soil compaction is a function of numerous variables such as vertical tire load, lug and cavity shape, tire width and diameter, bias or radial construction, dynamic loading, tire pressure, soil type, moisture content and wheel slippage. Soil compaction testing facilities utilize various methods for loading the tire, measuring compaction and tire-soil interface for a broad range of tires, loading conditions, soil moisture, etc.
Problem Statement
The proposed work is the design and fabrication of a tire test fixture to measure the influence of tire pressure, vertical and draw bar loads on soil compaction for agricultural and off-road tires. The fixture will apply calibrated vertical and draw bar loads. The stress distribution in the soil pan will be measured with pressure pads.

Water Management Modeling for Cold Start
Material Property and Segmented Cell Measurements The objective of this task is measurement of material and transport properties required as inputs for the Anode GDL Model and FEA Model being developed at Michigan Technological University (MTU) and Los Alamos National Lab (LANL) respectively.
GDL Modeling for Cold Start The objective of this task is to determine the most relevant GDL material and transport properties for enabling improved cold-start response. An existing water transport model for hydrophobic GDLs will be modified to accommodate hydrophilic anode GDLs in conjunction with state-of-the-art catalyst layers and membranes. The Anode GDL model will be used to develop a mechanistic understanding of anode GDL material properties that have a significant affect on low-temperature transient response and cold startup. GDL, MEA Model Integration The Anode GDL model is a 'local' model focused on a land-channel section of the GDL. This model can be used to track the location of the product water and where evaporation will occur. However the Anode GDL model cannot predict cell performance. The FEA model is a 'cell-level' model that can be used to predict performance response, but requires bulk property relationships for the GDL-FEA interface. For this task, the parameter output of the two models will be integrated. The Anode GDL model will, based on a land-channel unit cell provide bulk transport predictions as source terms for the FEA model. The FEA model will provide the flux conditions for the Anode GDL model. The model integration will be iterative and will need to be conditioned with single-cell experiments.
The objective of this task is to develop a design methodology, or design tool, that can be used to predict fuel cell performance for unique combinations of fuel cell component. Michigan Tech will work closely with LANL on this task. Model Validation This task is focused on the design and conduct single-cell experiments for the purpose of generating data sets specifically for model validation; as opposed to cell performance or durability testing. Experiments may incorporate segmentation in order to collect spatially and temporally varying current distribution and to potentially control voltage and current distribution for model validation purposes. The experiments will be conducted at 3M. Michigan Tech and LANL will provide guidance on experiment conditions to use for validation tests

Project Summary
Studying the nonlinear dynamics of fluid-structure interaction provides insights into a widespread physical topic which makes appearances in many scientific disciplines and several branches of Engineering. These phenomena manifest themselves at a wide range of scales and present excellent opportunities for scientific discovery with a richness of technical application. In cases like a rotor blade or an insect wing, where a body is subject to a complex motion due to the intrinsic operation of a certain mechanism or the dynamics of its control system, the scientific challenge is still greater.
The objective of the CAREER program proposed is to provide a better understanding of the underlying physics in slender-body aeroelastic dynamics through improved mathematical computational models of the multiphysics process. The program is divided into three overlapping phases each of them building upon previous work the PI has published. The first phase focuses on a new series of adaptive algorithms, based on the hybrid (or vorticity-velocity) formulation of the Navier-Stokes equations. The kinematic laplacian equation (KLE) technique will be used to create a complete decoupling of the two hybrid variables in a vorticity-in-time/velocity-in-space split approach. The resulting global scheme is intrinsically compatible with non-linear adaptive ODE algorithms, providing a way in which the submodels for the different problems involved (flow, structure, control-system dynamics, etc.) may be treated individually as rnodules that interface with the main ODE routine. This allows for the simultaneous analysis of the aeroelastic problem together with any innovative control strategy into a single computationally-efficient self-adaptive algorithm. The second phase consists of qualitative studies on vortex-shedding and wake dynamics behind oscillating bodies, which play a critical role in the aeroelastic problem. In the third phase, quantitative studies on prototypes of innovative wind-turbine blades, and their associated control strategies, will be conducted.
Intellectual Merit
The intellectual merit of this work is the advancement of computational mathematical models for the complex multiphysics problems involving fluid-structure-control interaction that are present in many engineering designs, providing also a fundamental tool for a better understanding of the underlying physics. The experimental analysis of these coupled multiphysics problems is extremely difficult. In some cases (like wind-turbine blades), huge size differences complicate extrapolation of experimental data from the wind tunnel to the prototype scale. In others (like the lifting surfaces used in Micro-Air-Vehicle applications inspired in the flapping-wing biological mechanisms observed in bird and insect flight), the sheer task of placing sensors on a small-scale mechanism in complex rototranslational motion becomes almost insurmountable. If
successful, the innovative mathematical models proposed here would improve the efficiency and flexibility of the computational implementation and provide a way to tackle these difficulties.
