Numerical simulation of supersonic turbulent combustion of hydrogen in a stream of hot humid air

The paper presents the results of solving the validation problem of turbulent combustion of a hydrogen jet in a supersonic flow of hot humid air in a symmetrical channel. Special attention is paid to the solution of the system of equations of chemical kinetics, which imposes a significant restriction on the time step, as well as the analysis of kinetic schemes used in the solution. The main computational difficulty is the detailed resolution of the wall region, due to the injection of a hydrogen jet into a turbulent boundary layer, in order to further reproduce experimentally obtained distributions of mole fractions and temperature in the outlet section of the channel, as well as the location of the ignition point.
