英文摘要	使用两步化学反应模型对连续旋转爆轰发动机(Continuous rotating detonation engine,CRDE)进行了二维数值模拟研究.数值计算获得了同轴圆管腔中间层曲面上连续爆轰的多个循环过程.分析了燃料入射、提前燃烧、爆轰波结构和波传播速度等几个关键问题.计算获得燃烧室内流场结构与之前实验研究结果定性符合.计算中燃料以最大1400m/s沿轴向入射,爆轰波可约以2400 m/s沿周向连续循环传播.计算的燃烧室内爆轰波循环频率约为2300Hz.; A two-dimensional numerical simulation of the continuous rotating detonation engine(CRDE)was carried out with two-step chimerical kinetic model.Multi-cycle process of continuous rotating detonation(CRDE)was numerically obtained on coaxial cylinder.Some key problems about CRDE,such as fuel injection,pre-combustion,detonation structure and propagating velocity were discussed.The simulation results agree well with the previous experiment results.A detonation wave can continuously propagate around at about 2400 m/s with maximum injection velocity of 1400 m/s.A CRDE keeps a high frequency of about 2300 Hz in this simulated combustor of 7 mm in radius.; 国家自然科学基金; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 6; 717-721; 30
