Description
A study of compressible subsonic/supersonic transitional and turbulent flow in a plane channel with isothermal walls has been performed using a spatially developing DNS (Direct Numerical Simulation). Random disturbance is artificially introduced at the inlet of the computational channel, which yields streamwise vortices and low/high speed streaks downstream. At high Mach number flows, the isothermal boundary conditions give rise to a flow that is strongly influenced by wall-normal gradients of mean density and temperature. These gradients are found to cause major differences of the transitional streak structure between subsonic and supersonic channel flows.
