$TKE amplification factor K as a function of the pre-shock Mach number M1 (upper solid line) for normal shocks propagating in low turbulence intensity air with only vortical deviations ( χ=0) at T1=300 K and P1=1 atm. The upper dashed line corresponds to the thermochemical frozen gas approximation.

Hypersonic flight involves a variety of complex flow phenomena that directly impact the aerothermodynamic loading of high-speed vehicles. The turbulence encountered during a typical flight trajectory influences and interacts with the shock waves on and around the surface of a vehicle and its propulsion system, affecting both aerodynamic and power p...
