Abstract
Modeling the mass transfer through the fracture-matrix interface is one of the critical issues in the simulation of transport in a fractured porous medium. A RWPT technique suitable for discrete fractured networks and capable of simulating conservative and reactive transport in fractured media is developed in this study. The particle tracking contaminant transport model, previously developed for simulating advection and dispersion processes in discrete fractures, is adapted to include matrix diffusion and reactive processes. Equations are developed to determine the relation between several controlling parameters to ensure model accuracy. The results indicate that the particle tracking model is performing well and provides an alternative to dual-porosity and dual-permeability models
