Abstract :
In this paper, the migration of LNAPL in unsaturated homogeneous porous media was simulated in a 2-D plexiglass tank. The movement of tinct LNAPL in porous medium was successfully traced by digital camera. The variation of aqueous phase, oil phase and gas phase pressure in the process of LNAPL leakage were measured by a pressure collection system. Furtherly discussed the mechanism of LNAPL emplacing aqueous and gas phase in unsaturated zone was important for prediction and remediation LNAPL in underground system.
