Permeability model
WebThe relative permeability concept is a useful approach to describe flow of one phase in existence of other phases. All rocks which represent hydrocarbon reservoirs contain more than one fluid flowing phase. Thus, relative permeability data are necessary for reservoir simulation studies. Web25. mar 2024 · As an intestinal barrier model, we used a confluent and polarized Caco-2 cell monolayer and assessed the ME-3-induced effect on paracellular permeability by transepithelial electrical resistance (TEER) and fluorescent-dextran flux assays. The integrity of tight and adherens junctions was examined by confocal microscopy analysis.
