摘要
Abstract
A two-phase reaction model of the secondary combustor was established to study the effect of primary water penetration angle on engine performance of magnesium-based water ramjet with secondary water penetration. The change tendency of specific impulse, temperature, velocity and pressure of nozzle exit were obtained with primary water penetration. Direct-connected tests were carried out in order to validate the correctness of the numerical simulation. The result shows that as the primary water penetration angle between 40° the specific impulse of water ramjet become better.关键词
