Abstract A general model describing the combustion of mixed gases is proposed, which accounts for the chemical work and assumes a single chemical reaction. An energy equation is written for an arbitrary mixture of fuel/oxidizer/combustion product. The combustion of an H2/O2 mixture is considered on the basis of the model. Modeling is carried out for two options: with and without account for the dependence of the heat capacity of the mixture components H2, O2, and H2O on temperature. The chemical work has a positive sign, and its relative contribution to the main characteristics of the process (temperature and burning rate) is estimated at 3.9 and 19%.
