摘要: |
采用空间二阶精度的交替方向隐式分解的 NND 格式求解完全气体假定下的非定常薄层近似 Navier-Stokes 方程, 并采用抛物化的椭圆型方程生成复杂带翼外形的空间网格。最后给出了类升力体外形在M∞=8.0,α=20°下的流场计算结果。 |

Abstract: |
Using alternating direction implicit NND scheme, the TLNS equations were solved under the assumption of perfect gas, and the space grids of complex wing-shape were generated by solving parabolic partial differential equations. Finally, the numerical simulation results of liftbody-type were shown under the conditions: M∞=8.0,α=20°. |
Keywords: liftbody-type hypersonic flow numerical simulation Navier-Stokes equations |
