以氢氧混合气为例，对会聚发散喷射器脉冲爆震发动机进行了数值模拟。得到了不同喷射器喉道面积比对PDE性能的影响规律。结果表明：脉冲增大比越大，喉部面积比越小，二次流质量流量随喉部面积比的增大而减小；
Taking hydrogen-oxygen mixture for example,the pulse detonation engine(PDE) with converging-diverging ejector was simulated numerically.The rule of different ejector throat area ratio influence on PDE performance was obtained.The results indicate that the more impulse augmentation ratio the less the throat area ratio,mass flow rate of secondary stream decreases with the throat area ratio.
