Abstract
The interaction of the cooling systems of permeable materials with a high-temperature gas flow is considered. The effect of the porosity and thermal properties of some metals on heat transfer is studied. It is found that increasing the thermal conductivity of the material leads to a decrease in the temperature of the heat-shielding coating and increasing the porosity to a more uniform distribution of the coolant applied on the surface and to a decrease in the heat loads on the structure to be protected.
