Convection of ternary mixture in anisotropic porous medium

Abstract

The paper presents the results of modeling convection in the layered structure of a hydrocarbon field. A horizontally elongated rectangular cavity of a porous medium, which consists of two layers with equal porosity and different constant permeabilities, is considered. The cavity is filled with a homogeneous ternary hydrocarbon mixture. The problem is solved within the framework of the Darcy-Boussinesq model, taking into account thermal diffusion. Data on convective regimes and distribution of mixture components were obtained in cases when the ratio of the permeabilities of the lower and upper layers is greater or lower than unity.
