Zhiwen joined the Thermal Sciences Group in 2009 to work in the field of concentrating solar power. His experience includes combustion, fluidization, hydrogen and fuel cells, electronic thermal management and packaging, and gas turbines. He taught in the Department of Engineering Mechanics at Tsinghua University for three years, conducted multiphase flow research, and developed pyrometer techniques for measuring gas turbine temperatures. Beginning in 2001, he was a test and modeling engineer in fuel cell energy, and worked on molten carbonate fuel cell performance and life improvement for cost reduction. He was also involved in the Solid State Energy Conversion Alliance program, supporting the testing and modeling of solid-oxide fuel cell stacks and system design.
Zhiwen has published papers and a book chapter, and was awarded two patents in the areas of fuel cells and thermal fluids. Before joining NREL, he worked for GE Aviation on gas turbine flow and heat-transfer design. He works on system analysis, measuring the properties of heat-transfer fluids, and developing thermal-storage concepts for concentrating solar power technology.
