George R. Brown Distinguished Professor, Mechanical Engineering
Professor Kee holds the George R. Brown Distinguished chair. Dr. Kee’s research interests are primarily in modeling and simulation of chemically reacting fluid flow. Applications are generally in the area of clean energy, including fuel cells, photovoltaics, and advanced combustion.
Dr. Kee’s sponsored research efforts are primarily in the modeling and simulation of thermal and chemically reacting flow processes, with applications to combustion, electrochemistry, and materials manufacturing. His fuel-cell research concentrates on elementary chemistry and electrochemistry formulations and their coupling with reactive fluid flow. Primary applications are to solid-oxide fuel cells operating on hydrocarbon fuels. His combustion research emphasizes the use of elementary chemical kinetics to understand fundamental flame structure.
Recent research includes efforts on catalytic-combustion and water-mist flame suppression. The materials-processing efforts emphasize the design, optimization, and control of chemical-vapor-deposition processes, with applications ranging from thin-film photovoltaics to CMOS semiconductor devices. The work includes development of computational methods and software to solve systems of stiff differential equations. It also includes development of an extensive system of general-purpose chemical-kinetics and molecular-transport software.
Dr. Kee is the principal architect and developer of the CHEMKIN software, which is the leading software package used worldwide for simulating chemically reacting flow.
