Numerical simulation of turbulent combustion of subsonic gas jet flows

A physical and mathematical model of turbulent combustion of subsonic gas fuel jet flows flowing into an air space is proposed. The processes are described by averaged equations of the boundary layer with a turbulent viscosity model and a combustion diffusion model. As turbulent viscosity models, the well-known two-parameter k -ɛ standard and k -ω models are taken. The results of the averaged and pulsating flow characteristics’ comparison of numerical calculations with the experimental data are presented.
