This field of study deals with the dynamics of high-speed flows, often exceeding the speed of sound by a factor of 6.

Special phenomena in this flow regime includes shock waves, expansion fans, flow chokin, viscous heating, and so on.

Primary objective is to develop an efficient vehicle that flies in this envelope.

High energy-density requirement in propulsion technique still necessitates efficient combustion-based systems. 

Especially in compact systems, the combustor must be capable of flame holding and fast chemical processes for maximized performance.

The aim of the studies include novel flameholding strategies and combustor designs, fuel thermochemistry, liquid spray characterization and so on.
