| 摘 要： | 采用一种混合大涡模拟/雷诺平均Navier-Stokes(LES/RANS)模拟方法结合三阶加权基本无振荡(WENO)格式对马赫数为2.88的压缩斜坡流动进行了数值模拟,并采用"回收/调节"方法生成入口湍流脉动边界条件.当采用固定入口边界条件时,湍流边界层会缺乏合理的湍流能量,使之抵抗逆压梯度的能力减弱,会严重高估分离...

| Abstract: | A hybrid large eddy simulation/Reynolds-averaged Navier-Stokes(LES/RANS) simulation method together with the third-order weighted essentially non-oscillatory(WENO) scheme were used to compute the flow field of a Mach number is 2.88 compression ramp flow.A recycling/rescaling method was used to generate turbulent fluctuating inflow boundary conditions.When fixed inflow boundary conditions were applied,the incoming turbulent boundary layer could not resist the adverse pressure gradient due to lack of reasonab... |
