Abstract

In this paper, we analyze the hydrogen combustion and heat transfer in the combustion chamber in an oxygen environment with forced cooling of the combustion chamber. We simulated the combustion of a previously unmixed mixture of fuel and oxidizer with allowance for dissociation processes. The main parameters and composition of the combustion products are determined for different geometric dimensions of the combustion chamber and the excess oxidant coefficients. An increase in the internal diameter and length of the combustion chamber with an unchanged hydrogen consumption is shown to lead to a reduction in the actual underburning. In this case, the actual underburning is significant due to the dissociation of combustion products at high temperatures. The effect of oxidizer excess on underburning and the temperature of combustion products is studied.
