Abstract: The efficient fuel injection system is a vital part of scramjet for a high-speed flight. In this scientific study, the effects of the multi fuel jets on the inclined surface are investigated at the supersonic air stream with Mach=4. This study employed the CFD technique for the simulation of the interaction of multi hydrogen-jets with free stream airflow. The impressions of inclined surface angle and hydrogen jet total pressure on the fuel mixing zone are disclosed. The Mach contour on the jet plane is presented to describe the chief terms on the distribution and penetration of hydrogen jet inside the combustion chamber. To perform a 3D computational study, the RANS equation with the SST turbulence model is used. Our study shows that the mixing performance of multi jets enhances in high jet pressure when the angle of the tending exterior is raised. Our findings also demonstrate that power and slant of the separation shock is highly effective on the size of the mixing zone.
