Pollutant Transport Modelling in Partially Saturated Deformable Porous Media

Abstract

The main scope of this article is to carry out a mathematical framework and its corresponding finite element discretization for the solution of pollutant transport in partially saturated soils. A multi- phase system with the interstitial voids in the grain matrix filled with water (liquid phase), water vapour and dry air (gas phase) and with pollutant substances, is assumed. The ensuing mathematical model involves equations of momentum balance, energy balance and mass balance of the whole multiphase system. Encouraging outcomes were achieved in several different examples.
