Heat and contaminant transport in unsaturated soil

Solute transport in unsaturated porous media can be viewed as a coupled phenomenon with waterand heat transport, together with mechanical behaviour ofmedia. in this paper, solute transport is formulatedmathematically considering heat and water flow in deformable porous media. advection, dispersion anddiffusion of chemical species in the liquid phase are considered. convection and conduction for heat flow istaken into account. waterflow is considered in both vapour and liquid phases. equilibrium equation, energyconservation, mass conservation and linear momentum jar watel; gas and solute are written and solvedsimultaneouslv using finite element method. the developed model is validated bv solving some examples andcomparing results with the results of experimental observation.
