Abstract

Characterization of DNAPL (Dense Non-Aqueous Phase Liquids) penetrating process near source zone gives suggestions to make measures against the groundwater contamination and remediation. The study aims at formulating mathematical model for realizing DNAPL droplets behavior using random-walking with entrapped detention factor by capillary pressure. Comparing fingering model based on the invasion percolation theory with experimental data, the results presented that the entrapped coefficient λ, which is a characteristic parameter in the proposed DNAPL migration model, is related to both capillary number and bond number.
