This research presents a mechanical model for simulation of mass removal during multi-phase flow on subsurface, such as pollution advection, CO2 geo-sequestration and air sparging. Proposed model includes hydrodynamics of air and water phase ; calculated air volume content is divided into a number of air channels surrounded by the water phase, which is divided into two compartments. First compartment is immobile and it is in contact with air phase, while the second compartment is mobile. This "mobile-immobile" formulation is a common approach for description of solute transport by groundwater. Moreover, the two-phase (water and air) numerical model which considers the thermal and the dissolved oxygen process are developed.

本文提出了一个模拟地下多相流过程中物质去除的力学模型，如污染物平流、CO2地质封存和空气喷射。所提出的模型包括空气和水相的流体动力学，计算的空气体积含量被划分为多个由水相包围的空气通道，它被划分为两个隔间。第一隔室是不移动的并且其与空气相接触，而第二隔室是移动的。这种“动-不动”公式是描述地下水溶质运移的常用方法。建立了考虑热力和溶解氧过程的水气两相流数值模型。
