在文献［1］结合NND格式思想［2］提出的有限元格式基础上，给出一种有限差分－有限元混合方法。通过求解完全Navier－Stokes方程，得到了高超声速情况下钝头体轴对称绕流的较满意结果，同时讨论了网络Re数对驻点热流的影响。
Based on the finite element method proposed in the literature [1] combined with the idea of NND format [2], a finite difference-finite element method is presented. By solving the complete Navier-Stokes equation, a more satisfactory result of the symmetric flow around the blunt body is obtained under hypersonic conditions, and the effect of Reynolds number on the stagnation heat flow is discussed.
