摘要
本文针对两相不混溶驱动和两相混溶驱动问题,提出了两类处理对流项的新方法:粘性分离算法和任意网格上的迎风算法,给出了理论分析,模型问题的试算得到满意的结果。
In this paper, for the two 'phase immiscible and miscible displacement problems we propose two kinds 'of new numerical methods: the viscosity splitting method and the upwind difference method over arbitraty triangulation pratitions, and discuss their theoretical analyses . The numerical results are very efficient and reasonable for model problem.
