摘要 介绍了连续爆轰发动机(Continuous detonation engine,简称CDE)的物理模型及爆轰波传播的物理机理,并对CDE流场的波结构进行了分析.使用两步化学反应模型对简化的CDE模型做了二维数值模拟研究.计算了圆柱面展开二维平面的多个爆轰循环过程.模拟结果较好地匹配了相关CDE实验所获得的流场结构.数值计算结果使我们可以更加透彻地理解CDE各方面的参数,对于CDE的进一步研究具有一定的指导意义. Physical model and propagation mechanism of continuous detonation engine(CDE) were introduced.The wave structure of CDE was physically analysed.Two dimensional simplified model of CDE was simulated by two step chemical reaction model.The simulation results show a serial of detonation waves repetition processes along a 4 cm perimeter circle surface which is extracted from the cylindrical combustion chamber.The simulation results of the wave structures agree well with the corresponding experimental results.Th...
