Problem 5 – Formation of residual NAPL saturation in unsaturated porous media

Abstract: The user is introduced to NAPL flow in porous media. The example problem demonstrates how residual NAPL saturation formation in the unsaturated zone affects NAPL flow. Residual saturation formation in the vadose zone is a process that is often ignored in multi-fluid flow simulators. The user will simulate an actual column experiment and evaluate the impact of residual NAPL saturation on fluid flow. The Water-Oil mode (STOMP4) is used for this application.
