摘要
采用 Gauss-Seidel迭代法 ,计算了超音速流体放大器的内部流场。流动控制方程使用雷诺平均 Navier-Stokes方程 ,湍流模式选用 Realizable k-epsilon湍流模式 ,近壁区用二层分区模型处理。数值模拟表明 ,超音速流体放大器的内部流场里存在射流偏转、流动分离和激波相交。
In this paper, the Gauss-Seidel method is used to calculate the inner fluid field of the supersonic fluid amplifier. The governing equations of flow are Reynolds Averaging Navier Stokes equation. The model of turbulence is Realizable k-epsilon model, and two layer zonal model is used near the wall. Numerical simulation indicates that there are several complex phenomena in the inner fluid field of the supersonic fluid amplifier, such as flow separation, jet deflection, shock wave intersection, shock wave reflection and so on.
