摘　　要：运用流体力学的基本原理,建立了爆震流场的数学模型,确定了CE/SE方法的守恒元与求解元,对氢氧爆震波的形成和传播过程进行数值模拟,并将计算结果与逐次迭代法计算结果和实验值作了比较,验证了时空守恒元和解元方法计算一维非定爆震流场的有效性与高精度。The mathematical model of one-dimensional detonation flow in pulse engine was established on the basis of fluid mechanics theory. The governing equations and conversation element,solution element were established. The numerical calculation of the formation and propagation process of oxy-hydrogen detonation wave was made, the result Was compared with iterative calculation result and experiment result, proved the CE/SE method is applicable to simulate the refined structure of oxy-hydrogen detonation wave.
