To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which is a minimum pressure for one liquid to enter a soil pore saturated with the other liquid, affects  DNAPLs migration in heterogeneous aquifer. The simulations of the HFE migration were conducted using COMSOL Multiphysics ver 3.5a.
