摘要：
A laminar compressible boundary layer on a permeable plate under blowing at small and large Prandtl numbers is investigated numerically. For Prandtl numbers Pr < 1 and the temperature of the gas blown lower than the temperature of the adiabatic impenetrable wall, the calculations carried out confirm the existence of a region of the permeable wall where the temperature is lower than the temperature of the blown gas. For Prandtl numbers Pr > 1 at a blown-gas temperature higher than that of the adiabatic impenetrable wall, the temperature of the permeable wall is higher than that of the blown gas.
