摘要

对一种后掠压缩斜板进气道(Caret进气道)的进口激波结构、进口流动对管道后部流场的影响进行了数值分析

对进口倒圆修形的影响、激波覆盖面也进行了讨论。数值模拟采用N-S方程和标准k-ε模型加壁面函数方法。计算结果表明:超音速情况下

由于进口存在较强的正激波

进口斜激波强度的不均匀性

对管道内部流动看不出有明显的不利影响;但两压缩面交角处的流动对管道后部流场有较大的影响。

Abstract

A numerical investigation was conducted about the shock structure at the entrance of the inlets and the effects of entrance flows on aft duct flowfields for a Caret inlet

and also the effect of the fillet circle and shielding region of oblique shocks.N S equations with the standard k-εturbulence model and near wall functions were employed to predict the flowfields.The results showed that asymmetry of oblique shock doesn't affect evidently duct flow due to the existence of strong normal shock.But the flow in the intersection of dual ramp affects evidently the flowfield of aft duct.
