Investigation of Salt Transport in Vertical Boreholes in Brine Invasion into Freshwater Aquifers. Technical Report

摘要

This report contains numerical and experimental studies convective-diffusive flow in wellbores and a numerical simulation of brine invasion of a freshwater aquifer. In the numerical study, comparisons of observed concentrations with values calculated from a one dimensional salt transport model demonstrated the model's adequacy in representing the salt transport. The experimental study generated data regarding salt concentration buildup in vertical tubes as a function of time. In the numerical simulation through comparison of several methods, the feasibility of using a high order finite difference method in multidimensional problems was demonstrated.
