In this paper, the authors deal with the numerical modelling for the one dimensional contaminant transport through saturated homogeneous and stratified porous media using mesh-free method and a numerical algorithm based on element free Galerkin method is developed.Abstract:
The present study deals with the numerical modelling for the one dimensional contaminant transport through saturated homogeneous and stratified porous media using meshfree method. A numerical algorithm based on Element free Galerkin method is developed. A one dimensional form of the advective-diffusive transport equation for homogeneous and stratified soil is considered for the analysis using irregular nodes. A FORTRAN program is developed to obtain numerical solution and the results are validated with the available results in the literature. A detailed parametric study is conducted to examine the effect of certain key parameters. Effect of change of dispersion, velocity, porosity, distribution coefficient and thickness of layer is studied on the concentration of the contaminantread more
