Numerical Investigation of NAPL Behavior at Heterogeneous Sand Layers Using VODA Multiphase Flow Code

Popis výsledku v původním jazyce

Interplay between the gravitational and capillary pressure forces at the interfaces of sands with different capillarity properties determines the fate of nonaqueous phase liquids (NAPLs) in the subsurface. Competition of these two forces can be observedon inclined interfaces of homogeneous sand formations. We have developed a multiphase flow code that has been applied to the study of NAPL behavior at these interfaces. This model provides two methods for numerical treatment of sharp interfaces between the sands with different capillarity properties Numerical results are presented indicating domains of applicability of these methods and their ability to describe discontinuous saturation profiles across the interface. The model is applied for computationof two-phase flow in a layered medium containing an inclined interface between two homogeneous layers with different capillary pressure parameters.
