MATHEMATICAL MODEL OF THE «PISTON» DISPLACEMENT OF IMMISCIBLE LIQUIDS DURING FILTRATION IN A POROUS MEDIUM

Abstract

Mathematical model of the front displacement in porous media multicomponent systems, presents filterable immiscible (including abnormal) fluids. In real application tasks it is given a qualitative description of the process of displacement in a multicomponent system with an intermediate agent «piston». Mathematical model of a class of problems of the frontal displacement for multicomponent systems is formulated as a variation inequality and provides a simple numerical implementation.
