Effects of single-fracture aperture statistics on entrapment, dissolution and source depletion behavior of dense non-aqueous phase liquids

► A modified continuum-based model to simulate DNAPL migration and entrapment. ► Larger standard deviation and smaller correlation length lead to more mass trapped. ► A simple source depletion function describes DNAPL dissolution in open fractures. ► Closed bottom boundaries lead to large NAPL blobs that cause significant tailing.
