Abstract: Based on the theory for multiphase flow in porous media, analytical model for NAPL transport in soils is proposed and developed; and the transport behavior of NAPL in unsaturated soils and groundwater system is analyzed. Numerical simulation is employed to model the transport processes of LNAPLs and DNAPLs in subsurface system; and tempo-spatial distribution of NAPL and contamination extent are obtained. Numerical results show that the contamination characteristics of NAPLs can be reasonably described, which is significantly affected by intrinsic permeability of soils and residual saturation of NAPLs.

Key words: non-aqueous phase liquids (NAPLs), numerical simulation, contaminant transport, geoenvironmental engineering
