Turbulent Heat Exchange on the Surface of a Sharp Plate at a Supersonic Flow.

The results of calculations of the convective heating of a sharp plate placed in a supersonic flow at a speed of M = 6–8 are presented. The NERAT-2D code is used for calculations, which implements the Reynolds-averaged Navier−Stokes equations, together with Baldwin–Lomax and Prandtl algebraic models of turbulence. Good agreement is shown with the experimental data for convective heating in a turbulent boundary layer. The distribution of gas-dynamic functions is analyzed in different cross sections of the plate within the flow. [ABSTRACT FROM AUTHOR]
