Assistant Professor

Mechanical and Aerospace Engineering

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.

Dr. Sirignano is interested in combustion theory and computational methods, fluid dynamics, multiphase flows, and propulsion and power.

His current research activities address the problems of the vaporization and burning of liquid fuels in very small volumes, turbulence-droplet interactions, distortion and breakup of thin liquid streams, flame spread across liquid fuel pools, and a study of combustion in high speed flows. The applications of the research include miniaturization of combustors, spray technologies, fire safety, and a new high-performance technology for combustion in the turbine stages of a gas-turbine engine.

Dr. Sirignano leads the Combustion, Fluid Dynamics and Propulsion Group and is the director of the Spray and Droplet Science and Technology Center at UCI.
