難解

Phenomenological Meniscus Model for Two-Phase Flows in Porous Mediahin pores in the form of a repetitive field of mobile menisci. These phase interfaces give rise to the appearance of a new term in the momentum balance equation, which describes a vectorial field of capillary forces. To derive the model, a phenomenological approach is developed, based on introducing

Dynamic Capillary Pressure Mechanism for Instability in Gravity-Driven Flows; Review and Extension t conservation of mass of water, and a generalized linear law for water flux (Darcy‘s law) containing a term called the dynamic capillary pressure. The distinct form of each alternative model is based on the specific form of expression used to describe the dynamic capillary pressure. The conventional

Analytic Analysis for Oil Recovery During Counter-Current Imbibition in Strongly Water-Wet Systems forces such that the non-wetting phase moves in the opposite direction to the water. We use an approximate analytical approach to derive an expression for saturation profile when the viscosity of the non-wetting phase is non-negligible. This makes the approach applicable to water flooding in hydroc
