| 摘 要： | 借鉴典型三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三维进气流道,并采用三维雷诺平均N-S方程和Spalart-Allmaras湍流模型对其流场进行了数值研究.计算结果表明:与三维超声速进气道中的平直激波系不同,三维进气流道中的激波为曲线激波;与二维进气流道中的激波系相比,三维进气流道中的激波系要相对模糊和复杂;转速和背压对三维进气流道的性能有较大影响.

| Abstract: | According to the design method of a typical three dimensional supersonic intake,a kind of three dimensional flow-path of a ram-rotor was designed.The three dimensional Reynolds-averaged Navier-Stokes equations and the Spalart-Allmaras turbulent model were adopted to simulate numerically the flow field of the designed three dimensional flow-path of the ram-rotor.It has been found that,unlike the linear shock wave system in three dimensional supersonic intake,the shock wave in the three dimensional flow-path ... |
