Effect of combustion on flow and heat transfer in a protective air jet and elimination of this effect on the thermal state of the wall

This paper studies the dependence of the equilibrium parameters of the gas on the coolant injection rate in jet cooling under conditions of combustion in a protective layer. Results are preented from empirical determination of the thermal state of the walls of cooling sections of different lengths and the temperature fields of the gas mixture with combustion in a protective layer and in the absence of this layer. The conditions are determined under which combustion in the protective layer has almost no effect on the thermal state of the wall
