| dc.description.abstract | An ex-situ soil contamination cleanup technique is developed. The physical system which embodies a set of two dimensional partial differential equations for underground water are solved. These equations, however, consist of water continuity equation, x and y Darcy's momentum equations, surfactant equation, and contaminant equation. The surfactant and contaminant equation are coupled via Wilson's isotherm. The developed method is found very efficient and the results are consistent with a simple model which is also solved numerically to validate the results. Eight Cases are discussed which have different operating and inlet and outlet conditions. Cases which have inlets and outlets at the same level are found to take longer time than those which have inlet and outlet at different levels for the contaminant to be cleaned up entirely. The time is related to the total volume of surfactant solution flowing through the system. | |
