摘要

摘要: 借鉴二维超声速进气道的设计方法,设计了一种旋转冲压压缩转子的二维进气流道,并采用二维雷诺平均N-S方程和Spalart-Allmaras湍流模型对其流场进行了数值仿真,研究了转速、背压对二维进气流道中波系结构、内部流动特性和性能的影响.计算结果表明:所提出的旋转冲压压缩转子二维进气流道设计方法是可行的;二维进气流道中产生的激波系与二维超声速进气道中产生的激波系相类似,所不同的是二维进气流道中产生的激波为弯曲激波,而二维超声速进气道中产生的激波为平直激波;转速和背压对二维进气流道的性能有较大影响.

Abstract: According to the design method of 2D supersonic inlet,a kind of 2Dflow-path of a ram-rotor is designed.The 2D Reynolds-averaged Navier-Stokes equations and the Spalart-Allmaras turbulent model are adopted to simulate the flow field of the designed 2Dflow-path of the ram-rotor.The influence of rotational speed and the back pressure on the structure of shock wave,the characteristic of inner flow and the performance of the ram-rotor are researched.It has been found that the design method of the ram-rotor flow-path presented in this paper is feasible.The shock wave system in the flow-path is similar to that in the 2Dsupersonic inlet.The difference is that the shock wave in the flow-path is curve shock wave,and the shock wave in the 2Dsupersonic inlet is line shock wave.The back pressure and the rotational speed have great influence on the performance of the 2Dflow-path.
