Problems and Issues of Constitutive Relationships Needed for Accurate Modelling of Multiphase Flow in Heterogenous Porous Media

摘要: The movement of liquids that are immiscible with water through the vadose zone as well below table (Figure 1) is an important part contaminant hydrogeology. NAPLs may have greater densities (Dense NAPLs, or DNAPLs) than less (Light LNAPLs). They be partially soluble in so a dissolved phase nonaqueous present. Two flow occur including and DNAPL 1a). Three-phase air, NAPL phases 1b). generally hazardous, therefore require time consuming precautions taken when performing controlled laboratory (column, bench technical scale experiments) field experiments.
