Abstract
It is well known that NAPL is trapped in soil when NAPL infiltrates into unsaturated soil and that NAPL residual saturation influences the distribution of NAPL. However any paper hasn’t conducted the numerical simulation for air-NAPL-water multi-phase flow with NAPL residual saturation, until now. Therefore the this paper conducted the simulations for air-water-NAPL multi-phase flow with NAPL residual saturation and compared the results of the simuations and the results of experiments with a chamber for NAPL infiltration. As a result, it was found in this paper that the distrubtion of NAPL saturation could almost simulate with the NAPL rediual saturation.
