Abstract�� The combustion-heater was used to get high enthalpy, high mach number flow field in scramjet test. The injection is very important for the uniformity of the out-flow field. A three dimension numerical simulation software named Fluent was used to calculate the two injection. By examining the injection boundary, stream wise vortex etc., the mixing and combustion efficiencies of two injections were compared, and the results show that the performance of the hydrogen multi-hole oblique injection is predominated over that of the hydrogen single-hole vertical injection.
