The research goal is to adapt the algorithms developed at ITM NASU&SSAU to calculations of deceleration and mixing the chemically reacting flows of a viscous gas through channels, to test the algorithms, and to study deceleration of a supersonic flow through channel without considering combustion. The research method: calculations and analysis. The results obtained. Software and methodic support developed at ITM NASU&SSAU for a model of the Navier-Stokes parabolized equations is adopted for calculations of two-dimensional non-equilibrium chemically reacting turbulent flows of the gas mixture through channels. According to numerical calculations the SALSA and Nut-90 turbulence models are chosen. The efficiency of using the distributed mass input for deceleration of a supersonic flow through channel is numerically demonstrated. The dependency of the characteristics of the flow field through channel on the turbulence model used in mixing a supersonic concurrent air flow and subsonic jets of carbon fuel is shown. Applications: thermogasdynamical processes through channels and gas dynamical passages of ramjets.
