非结构网格上二维欧拉方程的多重网格解

Multigrid Solution for the 2 D Euler Equations on Unstructured Meshes

介绍了在非结构三角形网格上对欧拉方程进行有限体积离散的一种方法⒚通过运用一系列彼此独立的粗细不同的非结构网格，即多重网格算法。

A finite volume discretization of the Euler equations on unstructured triangular meshes is presented. Convergence has been accelerated by an unstructured multigrid algorithm which operates on a sequence of completely unrelated unstructured coarse and fine meshes. Subcritical and supercritical flows are computed about multi element airfoil configurations in two dimensions. The computation results are compared both with an exact potential flow solution for a low Mach number case and with experimental data for a case with small viscous effects. And it shows that the multigrid algorithm is very efficiently.
