Taylor’s Dispersion Approach for Modelling Contaminated Solute Transport in Soil Through Two Immiscible Fluids

Our environment is surrounded by land and water. Everyday activities of humans have an adverse effect on the environment. The leachate water from landfills, industries and companies are passed through water and soil every day. So, it is crucial to understand how the contaminants are transported through the soil from polluted water. This paper depicts the transportation of contaminants through two immiscible fluids in two sub surfaces of the soil region (Top Soil and Parent Rock). Taylor’s dispersion method is employed to study the concentration of the contaminants in both sub surfaces. The model contains key parameters such as fluid velocity, density, coefficient of thermal expansion and temperature which helps in understanding the contamination of soil through two layers. This model also elaborates the effects of different heights, diffusion coefficient and various values of dynamics viscosity affecting the concentration profiles through graphs.
