NUMERICAL STUDY OF THE EFFECT OF INJECTION MODELING ON MIXING AND FLAME STABILITY IN SUPERSONIC COMBUSTION

The present study describes a numerical study on mixing and flame stability of hydrogen in supersonic airflow using injection modelling. 3 cases of injection model including 1 injector, 2 injectors and 3 injectors are considered. For these cases, numerical results are obtained by solving N-S equatio...

Zusammenfassung:The present study describes a numerical study on mixing and flame stability of hydrogen in supersonic airflow using injection modelling. 3 cases of injection model including 1 injector, 2 injectors and 3 injectors are considered. For these cases, numerical results are obtained by solving N-S equations, turbulence model and finite rate full chemistry of hydrogen-air using a high order numerical method. Temperature, flow field and mole fraction of all species are derived for all 3 cases. The results show a strong change in flame configuration for the 3 cases due to strong change in flow field.
