Sunil Mehendale is an Assistant Professor in the School of Technology at Michigan Technological University.  Prior to joining Michigan Tech as a faculty member, he worked for Carrier Corporation, Syracuse, NY as a Staff Engineer and Scientist in the Heat Transfer Technology and Components group.  There, he was responsible for developing and implementing advanced heat exchanger technologies as well as state-of-the-art design and simulation tools in the areas of energy efficiency, heat transfer, and fluid flow.  Before Carrier, he worked for seven years at Delphi Thermal Systems, Lockport, NY, where he was engaged in the research, design, and development of advanced energy-efficient heat exchangers, primarily evaporators for automotive climate control systems.  Before joining Delphi, Dr. Mehendale worked as a post-doctoral research associate in the Department of Mechanical and Industrial Engineering at the University of Illinois, Urbana-Champaign, where he designed and developed micro-scale heat exchangers intended for US military personnel in a project sponsored by DARPA, US Department of Defense.

Dr. Mehendale’s area of teaching and research interest and expertise is primarily in the thermal-fluids sciences, with emphasis on the design and optimization of high-efficiency energy conversion systems and heat exchangers, boiling and condensing flows, and two-phase flow distribution in heat exchangers, as well as alternate energy resources / technologies such as solar energy, wind energy, fuel cells, and biofuels.

In addition to teaching and research, Dr. Mehendale is a member of ASME, ASEE, and ASHRAE.  He also serves as a reviewer for the ASME’s Journal of Heat Transfer and the ASME’s Journal of Thermal Science and Engineering Applications.
