Numerical modelling of double diffusion driven reactive flow transport in deformable fluid-saturated porous media with particular consideration of temperature-dependent chemical reaction rates

摘要

Numerical methods are used to solve double diffusion driven reactive follow transport problems in deformable fluid-saturated porous media. In particular, the temperature dependent reaction rate in the non-equilibrium chemical reactions is considered. A general numerical solution method, which is a cocombination of the finite difference method in FLAC and the finite element method in FIDAP, to solve the fully coupled problem involving material deformation, pore-fluid flow, heat transfer and species transport/chemical reactions in deformable fluid- saturated porous media has been developed.
