The research goal is to choose adequate models of turbulence and parameters of a kinetic model of combustion on the basis of a comparative analysis of calculated data (ITM, NASU&SSAU) and experimental data (TsAGI and R&D Institute for Mechanics, MGU). The research method includes calculations and analyses. The results are obtained. Program and methodic support developed at ITM, NASU&SSAU for calculations of a 2D non-equilibrium chemically reacting turbulent flow of a gas mixture through channel is adapted and tested. The effects of selection of the turbulence model, kinetics of combustion, a geometric form of the channel and different methods of delivery of combustible components mixture to an air flow on the flow characteristics in deceleration of a supersonic flow through channel are numerically studied. Rational models and algorithms of a numerical simulation of the flows under consideration are formulated for engineering practice. Scientific novelty of the results is to determine by calculation features influence backpressure supply mass and burning the structure of supersonic flow when braking in the channels of various shapes. Recommendations on choice of turbulence model and the kinetic model of hydrogen combustion in a concurrent flow of air for an adequate description of these flows are formulated. The new information about the features of the braking process of supersonic flow in the channel and the impact on him of leading the masses is obtained. Recommendations on the use of the theoretical results to determine the flow parameters when braking in the channels are formulated. Applications: thermogasdynamic processes through channels and gas dynamic passages of ramjets.
