Turbulent Schmidt and Prandtl Numbers in the Boundary Layer on a Wall with Film Cooling when a Foreign Gas is Injected through a Porous Insert

Abstract

Variations in the turbulent Schmidt and Prandtl numbers in the boundary layer on a wall with film cooling when helium is injected into xenon flow through a porous insert is investigated numerically using the three-parameter RANS turbulence model supplemented with transport equations for turbulent heat and mass transfer. The results obtained are compared with calculated data for constant turbulent Schmidt and Prandtl numbers.
