| 摘 要： | 根据脉冲爆轰发动机内脉冲爆轰的特点,建立三维两相爆轰的理论模型。应用国际上最近发展起来的CE/SE方法,数值模拟爆轰管内三维两相燃烧转爆轰的过程。计算结果表明:当点火起爆后,在燃烧转爆轰过程中,三维效应非常明显。当形成稳定爆轰波后,三维效应不明显。计算压力值和实验压力值符合得较好。

| Abstract: | According to the characteristic of pulse detonation inside the pulse detonation engine,the three-dimensional models for two-phase detonation were built.The CE/SE method was used to calculate the deflagration to detonation.The cal-culation results show that the pressure field inside the tube is three-dimensional variation during the deflagration to detonation.When it is detonation wave,three-dimensional effect degenerates to be two-dimensional.The pressure data agree well with the experimental data. |
