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 =2 0°下的流场计算结果。
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°.
