Hydro-dynamic Solute Transport under Two-Phase Flow Conditions

Abstract There are abundant examples of natural, engineering and industrial applications, in which “solute transport” and “mixing” in porous media occur under multiphase flow conditions. Current state-of-the-art understanding and modelling of such processes are established based on flawed and non-re...
