Keywords: unsteady rans, stabilization of combustion, supersonic flow

Fast technology for computation of non-stationary viscid flows is presented. It is based on explicit scheme with Fractional Time Stepping. For boundary layers, either “wall law” boundary condition or Local Dual–Time Stepping is used. Technology is applied to supersonic flow in chamber with combustion of hydrocarbon fuel in pseudoshock.
