REACTIVE TRANSPORT THROUGH POROUS MEDIA USING FINITE DIFFERENCE AND FINITE VOLUME METHODS
In this paper, finite volume method (FVM) and implicit finite difference method (FDM) have been used to solve multi-process non-equilibrium (MPNE) transport equation for reactive solute transport through porous media. A review of literature reveals that an analysis of MPNE transport model has not been carried out to study its performance for advection and dispersion dominant cases. The main objective of the present study is to asses the performance of both FDM and FVM in presence of high value of Peclet number (Pe) for reactive transport through porous media. It is shown that, in case of advection dominant transport (i.e. at high value of Pe), FDM numerical model remains stable and oscillation free, when the values of mass transfer and sorption rate coefficients are high. Further, FVM model is capable of simulating advection dominant transport irrespective of the values of mass transfer and sorption rate coefficient. This is established through simulation of the experimental data of Strontium.
