2D groundwater contaminant transport modeling by using the finite volume method on an unstructured grid system

摘要

This paper introduces a finite volume unstructured algorithm for groundwater contaminant simulation. The algorithm is developed using the direct finite volume concept constructed on an unstructured grid system. The cell-centered explicit conservative scheme has been adopted in numerical simulation. An example of groundwater contaminant transport simulation on a simple geometry is presented and results are compared with an analytic solution and the solutions obtained by using a finite difference method on structured grids. The direct finite volume method applied on an arbitrary unstructured grid system is found promising for modeling groundwater contamination transport behavior.
