Mathematical Modeling of Biogrout Process

Abstract

This project deals with the mathematical formulation of ow during grouting, specifically the Biogrout process in sand. The model takes cue from the contaminant transport model, wherein both the concentration of both the aqueous species(the reactants) and the non-aqueous species (the product that acts as the cementing material) are taken into account. The porosity is variable and thus is the hydraulic conductivity of the medium. The rate of reaction is varying as it is set to depend on the initial concentration of the reactants via a time decaying relation. The governing equations are discretized using Finite Dieffrence. The numerical scheme is implemented in MATLAB and relevant plots are obtained.
