Control of parameters and structure of detonation wave in a dual-fuel methane-hydrogen mixture

A generalized model of chemical kinetics of detonation combustion of stoichiometric dual-fuel methane-hydrogen mixture is proposed. It allows calculating the molar mass and internal energy of a mixture without calculating its detailed chemical composition. The model was verified within the framework of a numerical calculation of the cellular multifront structure of a detonation wave. The calculated size of the detonation cell, as well as the qualitative structure of detonation (irregularity of the cellular structure due to the formation of both primary and secondary transverse waves, and incomplete combustion of gas in the detonation wave) are in good agreement with experiment.
