Abstract—A CFD analysis of the combustion process of a scramjet engine having wall injector with cavity with a L/Dratio of 5 is carried out in this present study using FLUENT software. Both air intake and H2 injection are at Mach 2 speed and hydrogen is being injected upstream of the cavity. It is observed that a maximum temperature of 2100K can be achieved with the injection of H2 at Mach 2 speed with high thrust production and low shock formation.
Index Terms—Wall injector, Mach number, Scramjet, static temperature, static pressure.
