| 摘 要： | 根据膨胀波火炮的工作原理，采用“隔离体”方法分别对系统的后喷装置和发射装置进行单独建模。利用Fluent软件的自定义功能将内弹道程序嵌入到Fluent中进行耦合计算，准确地描述了计及后喷装置动态打开过程的内弹道过程。通过对不同类型的后喷装置流场的计算分析和性能对比，为膨胀波火炮后喷装置结构设计和性能优化提供了理论参考。

| Abstract: | Base on the work theory of rarefaction wave gun,the models for back blast mechanism and launcher were separately established by segregate body method,and the interior ballistic circle including the dynamic venting process of venting mechanics was accurately described by nesting the interior ballistic program in the Fluent software with its user definition function.By the calculation and contrast of different type back blast mechanism fluid fields,theoretical reference was provided for mechanic design and be... |
