This laboratory, centered in the Department of Mechanical Engineering at The Ohio State University, is led by Walter Lempert, Igor Adamovich, J. William Rich, and Vish Subramaniam. It has developed into a major center for experimental and theoretical research into fluids with substantial thermal mode and/or chemical disequilibrium, with an emphasis on aerospace and industrial applications, such as high-speed flow control, plasma-assisted combustion, molecular gas lasers, and plasma material processing.
The focus of the laboratory is on the physics of engineering environments such as electric discharges in gases, high temperature gas dynamic flows, gas lasers, and plasma chemical reactors. The work of the laboratory spans very basic studies of molecular energy transfer and chemical kinetics to the development of novel plasma chemical processes, special purpose gas lasers, and predictive models for the flow around aerospace vehicles. Emphasis is on collision-dominated, high density systems with vibrational and electronic mode disequilibrium.
