| 摘 要： | 应用 PHOENICS软件模拟了固体燃料冲压发动机 ( SFRJ)的冷流和以 HTPB、PS为推进剂的简单反应流。结果表明 :在相同入口条件下 ,燃烧使附着点明显前移 ,从而改变了流场结构 ;入口温度不影响冷流时的附着点 ,但在有反应情况下则有一定影响 ;在两种情况下入口流量对附着点均无影响。

| Abstract: | Cold flow field and simple reaction flow field of the combustion of HTPB and PS within the solid fuel ramjet (SFRJ) are simulated using PHOENICS program. The result shows that the reattachment point moves forward so that the flow field structure is altered in case of combustion. In case of cold flow, the reattachment point doesn't change with inlet temperature, but it does so in simple-reaction flow field. And it doesn't change with inlet mass flux in both conditions. |
