Nonisothermal multicomponent reactive transport model for unsaturated soil

A reactive transport model, applicable to multi-component chemical behaviour is developed; within the context of a thermal, hydraulic, and mechanical framework for porous media. The model is based on conservation of mass/energy principles for flow behaviour and stress-strain equilibrium for the mechanical aspects. The resultant approach is coupled with a geochemical model. The coupling of the transport and geochemical models is achieved through both non-iterative and iterative approaches. A series of applications are considered, via an assessment of numerical performance and an examination of qualitative responses. The model shows good convergence and computational efficiency (Case Study 2).
