Model Development}, journal = {International Journal of Numerical Analysis Modeling Series B}, year = {2012}, volume = {3}, number = {2}, pages = {109--125}, abstract = {Dense, non-aqueous phase liquids (DNAPLs) are common organic contaminants in subsurface environment. Once spilled or leaked underground, they slowly dissolved into groundwater and generated a plume of contaminants. In order to manage the contaminated site and predict the behavior of dissolved DNAPL in heterogeneous subsurface requires a comprehensive numerical model. In this work, the Crank-Nicolson finite-element Galerkin (CN-FEG) numerical scheme for solving a set coupled system of partial differential equations that describes fate and transport of dissolved organic compounds in two-dimensional domain was developed and implemented. Assumptions are made so that the code can be compared and verified with available analytical solutions.}, issn = {}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/ijnamb/274.html} }
