Abstract
The subsurface can be considered to consist of two phases - the macrophase and the microphase in the context of contaminant transport. The interparticle pore spaces constitute the macrophase with the intraparticle pore spaces constituting the microphase. The macrophase transport is, often times, nonlinearly coupled with the microphase transport. The solution of nonlinearly coupled macrophase and microphase transport is particularly challenging. A Crank-Nicolson Galerkin finite element model (CNGFEM) has been developed to simulate the macrophase transport nonlinearly coupled with the microphase transport. The model is stable and provides oscillation-free results when the mesh Peclet number 5.2Pe and the Courant number m ≤ ≈ 1Cr . The model predictions were also found to be in excellent agreement with experimental data obtained from literature.
