In order to investigate the effect of primary gas entrance angle on engine performance of water ramjet, based on eddy dissemination model, a 3-D multi-phase non-premixed combustion reaction model was established in a high level magnesium-based water ramjet, the influence of gas entrance angle on temperature distribution, variety of the mass fraction of magnesium in the afterburning chamber and specific impulse of water ramjet were also obtained. The numerical results show that several stream primary gases impacting in the center of water ramjet obviously increases magnesium-water reaction rate in the primary water penetration region, efficiently improves operating pressure and specific impulse of water ramjet, and also benefits for shortening the length of the afterburning chamber for the magnesium-water complete reaction.
