Yun Wang

Dr. Wang is interested in multi-phase multi-component transport, CFD, batteries, fuel cells, computational modeling, thermo-fluidics, and turbulent combustion.

Dr. Wang's work emphasizes exploration on fundamentals of the physicochemical processes in advanced energy systems. His current research activities focus on the computational modeling and experimental diagnostics of polymer electrolyte fuel cells (PEFCs). He has proposed a comprehensive PEFC model fully coupling flow, transport, and electrochemical processes as well as including a detailed MEA (membrane electrode assembly) model. Another contribution of Dr. Wang is development of a 3D dynamic model which considers all the major transient processes occurring in a PEFC, such as gas transport, water accumulation in the membrane, and electrochemical double-layer discharge. His recent work investigated the microstructures of carbon papers and carbon clothes and proposed a structure-performance relationship of gas diffusion layers, which is one step toward developing a science-based framework for selection of materials for next-generation, high-performance gas diffusion media.
