| 摘 要： | 利用数值模拟方法研究了不同混合室构型对RBCC引射模态性能的影响。分析了不同混合室构型的流场结构、引射性能和混合性能。结果表明在相同的工况下,扩张构型具有较大的引射系数,但是抗背压性能较差;收缩构型引射系数较小,但是抗背压性能最好。等截面构型性能居中。

| Abstract: | Numerical simulation was carried out to investigate the influence on the ejector performance of different structures of RBCC mixer. Flow structure,performance of ejecting and mixing was analysised. Result shows that under the same condition and inlet cross section area of the mixer, the diffusive structure has the highest ejector coefficient and the lowest anti-backpressure ability. The contraction structure has the lowest ejector coefficient and the highest anti-backpressure ability. The constant area structure is medium in performance. |
