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 multiprocess nonequilibrium (MPNE) transport equation for reactive solute transport through porous media. A review of the literature reveals that the performance of the MPNE transport model for advection- and dispersion-dominant cases has not been analysed. The main objective of the present study is to asses the performance of both FDM and FVM in the presence of high value of Peclet number (Pe) for reactive transport through porous media. It has been shown that in case of advection-dominant transport (i.e. at high values of Pe), the FDM numerical model remains stable and oscillation free, when the values of mass transfer and sorption rate coefficient are high. Further, the 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.
