James Karnesky, Ph.D., P.E., CFEI
Senior Associate
Thermal Sciences
  • Los Angeles

Dr. Karnesky specializes in combustion, fluid mechanics, thermodynamics, and heat transfer. He has performed numerical modeling and experimental measurement of slurry entrainment and rheology for application to nuclear waste transport. He has performed experiments on flame quenching and the limits of flame propagation, as well as computational modeling of vented explosions. He has made numerical and experimental investigations of the structure and propagation of gaseous detonations in confined spaces.

Dr. Karnesky has used numerical and experimental methods to investigate the structural response to explosions in piping systems for the nuclear and chemical industries, including thermal stress, elastic wave propagation, and plastic deformation. He has performed experiments involving pulsed detonation, rotating detonation, and gas turbine engines. He has also performed experiments involving the detection of buried explosives.

Prior to joining Exponent, Dr. Karnesky was a research fellow at the Air Force Research Laboratory in Dayton, OH and an adjunct professor of mechanical and aerospace engineering at the University of Dayton. He has also worked as a researcher at FM Global Research and at the Pacific Northwest National Laboratory.
