Numerical simulation of non-equilibrium efflux of a supersonic combustion products jet with water droplets adding is carried out on the basis of a two-speed and a two-temperature model of a continuous medium with using the marching calculation method. The afterburning mechanism of combustion products in air oxygen is modeled by the kinetic model, which includes 11 elementary chemical reactions. The simplest model for evaporation of water droplets is considered. The influence of components afterburning and water adding to the jet’s body on the change in jet thermal characteristics is numerically investigated.
