| 摘 要： | 对比研究了两种构型的支板火箭引射冲压发动机引射模态的瞬时掺混燃烧(SMC)三维掺混和反应流场，详细分析了静态海平面零马赫数情况下燃烧及构型对引射流场的影响，发现几何构型和二次燃烧的综合影响决定了引射掺混后流体的速度、总温、总压及引射流量，从而也主要确定了发动机的性能，其中构型因素主要决定了掺混的质量，从而决定了低速模态的性能。

| Abstract: | 3-D turbulent flows with and without secondary combustion of two configurations of Strutjet RBCC in ejecting mode were investigated. The effects of secondary combustion and configurations on ejecting flow in static sea-level and zero mach conditions were analyzed in detail. The conclusion is that the velocity, total temperature, total pressure and secondary air mass flow rate are determined by both effects of configuration and secondary combustion, but the mixing degree between primary and secondary flow is mainly controlled by configuration, and thus the performance of RBCC. |
