| 摘要: |
| 用有限体积法求解三维完全气体的Navier-Stokes方程, 并将通量守恒的分区计算方法和B-L湍流模型修正结合在一起, 捕捉到了间断处的分离涡、激波、膨胀波等流场信息。 |
| 关键词: 飞行器廓线间断, 分离涡, 激波, 分区网格, 湍流 |

| Abstract: |
| Finite-Volume method was used to solve the three-dimensional Navier-Stokes equations of ideal gas, and combine flux conservative patched method and B-L turbulence model correction to study this problem, capturing fluid field informations such as separation vortex, shock wave, expansion wave. |
| Keywords: discontinuous profile lines of vehicles, separation vortex, shock wave, patched-grid, turbulence |
