| 摘 要： | 建立了水冲压发动机燃烧稳定性计算模型，对一次进水水冲压发动机燃烧室内流场进行数值模拟。研究了燃烧室长度、水燃比、液滴直径等因素对水冲压发动机燃烧稳定性的影响。研究表明，适当增加燃烧室长度、采用多次进水以减小局部水燃比并选取适当的雾化器，有利于水冲压发动机的稳定燃烧。

| Abstract: | The flow field of a single injection water ramjet was calculated based on the model which was established in the paper. Effects of chamber length,water-fuel ratio and droplet size on combustion stability were researched. It is shown that increasing chamber length,multiple water in-jection to decrease local water-fuel ratio and choosing proper atomizer will benifit combustion stabi-lity. |
