中文摘要：

建立了带喷管的氢氧连续旋转爆震发动机的二维模型,对连续旋转爆震发动机的工作过程进行数值模拟。基于带化学反应的欧拉方程,采用Rever-Evans氢氧反应模型,利用一维ZND模型进行初场设置,模拟了氢氧连续旋转爆震发动机从起爆到实现爆震波连续旋转传播的过程。对计算得到的流场进行定量分析,计算出发动机燃烧室中爆震波传播速度为2920～3060 m/s,频率为29800 Hz,并利用进出口参数计算出发动机的推力和比冲,计算得到发动机的平均推力为267 N,平均比冲为355 s,同时与火箭发动机工作过程进行了比较。

英文摘要：

The two-dimensional models for hydrogen-oxygen continuous rotating engine with an expansive nozzle were built to study the engine. The Euler equation with chemical reaction,Rever-Evans HydrogenOxygen reaction model and the one-dimensional ZND model were used to compute the ignition process and the rotating detonation wave propagating in the engine. From the quantitative analysis of flow field,the detonation wave propagation frequency was 29800 Hz and rotating velocity range from 2920 m / s to3060 m / s. The average thrust and impulse were 267 N and 355 s from the inlet and outlet parameters of engine. The calculation results show the different ways between continuous rotating engine and rocket engine.
