摘要: 本文用特征线目的和有限差分目的相结合的数值目的来求解对流问题和对流占优扩散问题,提出了两个计算格式,并给出了数值例子。

Abstract: In this paper,we consider the numerical methods for solving convection problems and convection-dominated diffusion problems on the basis of combining the method of characteristics with finite difference method we presented two numerical schemes. Some numerical results are also given.
