Abstract
In this project we focused on Simulation of two-phase (gas-oil) flow in 2D anisotropic porous medium on unstructured grids by finite volume method.Since the permeability assumes to be full tensor, common discretization methods for pressure and flux equations couldn’t satisfy continuity conditions then a new method of discretization named continuous flux approximation introduced.In this new method, cell center pressure calculated by directly applying flux continuity conditions to control volume boundaries. In this project a ninepoint scheme is used, it means that for making the flux continuity conditions over each control volume in two dimensions all neighboring cells are involved.The reason...

Abstract
Continuous approximation of pressure and flux fields is one of main goals of simulating flow in porous media. To compute the pressure field in heterogeneous and anisotropic media using minimum memory and time, it is necessary to use a conservative flux-continuous scheme. Nowadays, one of the most efficient approaches to minimize the solving time of large-scale problems is parallel computing. In this research, a parallel algorithm for flux-continuous multi-point flux approximation (MPFA) scheme with full pressure support (FPS) is designed and implemented on unstructured triangular grids by cell-centered approach. In this work, 2D single phase flows are investigated. The results are presented...
