The Immiscible Displacement in Random Porous Media
Man Wang · Journal of Wuhan Textile University · 2011
In this paper,the fractal nature of Viscous fingeringin(VF) random porous media has been studied.The fluid transport is based on the deterministic method.The result shows that the topology and the geometry of the porous media have a strong effect on displacement processes.The cluster size of viscous fingering pattern in percolation cluster increases with the increase of iteration parameter n.When iteration parameter n ? 10,VF pattern does not change with n.The distribution of velocities normal to the interface of VF in percolation cluster is also studied.The sweep efficiency E increases along with the increasing of iteration parameter n and decreases with the network size L.
