| 摘 要： | 采用二维、时变、可压纳维-斯托克斯(N-S)方程计算喷管流动。流动可为无粘、层流或湍流。湍流模型可采用代数混合长模型,一方程和二方程模型。喷管形状为二维(平面或轴对称)。计算网格内点采用MacCormack显式格式。采用局部细网格,快速解法以及时间间隔光滑方法,以加速高雷诺数下收敛。边界点采用参考平面特征线格式计算,粘性项作为源项处理。给出了初步算例结果,与其它计算和实验数据比较,符合良好。

| Abstract: | Using two-dimensional time-dependent compressible Na-vier-Stokes equations,nozzle flows are calculated.The flow can be invi-scid,laminar or turbulent.Interior grid points are computed using the explicit MacCormack scheme.In order to speed up the convergence at high Reynolds number,the local fine mesh,quick solutions and extended interval time smoothing procedures are used.Boundary points are calculated using a reference plane characteristic scheme with the viscous terms treated as source terms.The preliminary results given agree with the other computations and experimental data. |
