In this work, a physical model and a Computational Fluid Dynamics simulation model in COMSOL software version 6.4 were used to simulate the two-stage transport of pollutants through porous Media. As for the physical model, it was manufactured in a laboratory to conduct practical experiments to verify two-phase flow through sandy soil. Kerosene (as a pollutant in this work) was pumped through the porous medium in different experiments at mixing ratios (100%, 85% oil to water), such that this stage represents the pollution stage. At the end of each pollution stage, the soil is washed by pumping clear water to represent the washing process. Based on standard statistical indicators, it was found that the Computational Fluid Dynamics simulation model consistently yields water-saturated ratio S1 and oil-saturated ratio S2 that are close to reality, with an acceptable error rate. This indicates the ability of Computational Fluid Dynamics models to simulate the complex two-stage pollutant transport process through porous media with high accuracy and in a short time, at lower cost and effort.
