Dr. Leylegian’s main interest is in combustion, specifically in the high-temperature chemistry of reacting flows. He has performed experimental and computational studies on flame environments, from simple flow fields to high-speed supersonic combustion ramjet (SCRAMJET) combustors. He has also been involved in studies of fuel reforming for engine cooling and fuel cell applications, and novel energy conversion technologies. He is also well-versed in the numerical simulations of these phenomena, using industry-standard codes.
