| 摘 要： | 本文着重研究了二元超音速进气道几种唇口内侧壁面分离流动控制结构,对进气口流场、几何喉道下游邻近截面的流场及其壁面附面层参数、进气道出口流场和性能的影响。并对唇口分离流吹除和吸除之后,进气口再附着点下游截面上的总压脉动压力均方根值分布及功率谱密度-频率特性进行了比较。

| Abstract: | The effects of lip separate flow and its control on the flow at the entrance of the inlet and the flow field in the section downstream of the geometrical throat of the inlet,and on its wall boundary layer parameters and flow field and inlet characteristics at the exit are mainly investigated.Comparisons of the R.M.S.distribution of the total pressure fluctuation and its power spectrum density downstream of the lip separation reattachment point with and without lip separation blowing and suction are also made in this paper. |
