| 摘 要： | 本文用有限体积Ｇａｌｅｒｋｉｎ法求解了跨声速二维欧拉方程。求通量运用了Ｏｓｈｅｒ格式，通过外插把原来只有一阶精度的逆风格式改进成二阶精度。并采用基于一性化流量的隐式格式和非结构化网格，使程序具有较高的收敛效率。

| Abstract: | A finite volume Galerkin solution of the transonic two dimensional Euler equations is presented. The upwind Osher scheme is used to calculate the fluxes which is developed from first order accuracy to second order accuracy by interpolation. Higher rates of convergence are obtained by using an implicit scheme relying on a linearization of fluxes and c-type unstructured meshes. |
