Experimental testing of interfacial coupling in two-phase flow in porous media

摘要: Abstract Two-phase flow through natural porous media is affected by the interfacial coupling that takes place across interfaces located in a medium. Such may be of two types: viscous and capillary. In this study, defining equations for capillary parameters have been constructed. Moreover, these equations, together with modified form Kalaydjian's transport used to analyze two-phase media. On basis analysis carried out, it argued has no effect on steady-state, cocurrent flow, only small unsteady-state, flow. suggested significant countercurrent Two methods were test theory. first method, data from cocurrent, experiments show experimentally determined values p...
