摘要： 针对爆震发动机的多维效应,利用CFD计算软件对单管脉冲爆震发动机进行了二维的数值模拟。以氢气和氧气混合物为例,仿真了爆震波在管内的传播过程以及传出管外后的流场情况。模拟所得的爆震波参数与文献中的计算结果和实验值基本一致,验证了模拟的正确性。爆震波传出爆震管后退化成一道激波,对该激波的流动情况进行了分析。

Abstract: To discuss the multi-dimensional characteristic of pulse detonation engine,CFD program is used to simulate single-tube pulse detonation engine.The simulation is carried out in hydrogen-oxygen mixture.The results show that pressure and velocity of simulated detonation are close to experimental results,and that detonation decaies to a shock wave as it moves outside the detonation tube.

Key words: Pulse detonation engine;Detonation wave;Numerical simulation
