| Research Abstract |
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.
