Universal model of heat transfer in system with penetrating cooling

The penetrating cooling is related to the most intensive means of the heat exchange regulation inside the porous matrix. However the theoretical analysis of the heat exchange causes serious difficulties due to the absence of the generally accepted approach to the selection of the geometrical scale of the porous channels and critical ratios for calculating the internal heat exchange coefficient. All these problems are correlated from the unified positions, which make it possible to formulate the universal heat exchange model in the penetrating shells. The most important parameters of the thermal protection system are identified by the processed mathematical model
