Abstract: 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.
