Abstract—
Combustion flow inside the channel of a model scramjet air inlet with transverse hydrogen fuel injection from the bottom wall is investigated. The OH-concentration and pressure distributions that replicate qualitatively the flow structure observed in experiments are obtained. Several different mechanisms of formation of shock waves in the investigated experimental facility are distinguished. In analyzing the structure of fuel jet, satisfactory quantitative agreement with the calculation results of other authors is obtained. It is shown that the shock-wave structure affects significantly combustion enhancement.
