Numerical study of two-dimensional supersonic hydrogen–air mixing layer is performed to
investigate the effects of turbulence and chemical additive on ignition distance. Chemical
reaction is treated using detail kinetics. Advection upstream splitting method is used to
calculate the fluxes, and one-equation turbulence model is chosen here to simulate the
considered problem. Hydrogen peroxide is used as an additive and the results show that
