Analysis of DNAPL migration in aggregated kaolin and sand using light transmission visualization (LTV) method

Physical model experiments based on Light Transmission Visualization (LTV) method were conducted to study and observe the migration of dense non-aqueous phase liquids (DNAPL) in both single and double-porosity soil mediums. DNAPL that used in the research is tetrachloroethylene (PCE). Aggregated kao...
