Multiphase fluid flow in a pore doublet is fundamental problem and important for understanding the transport mechanisms of multiphase flows porous media. During displacement immiscible two-phase fluids doublet, process influenced not only by capillary viscous forces, but also channel geometry. In this paper, mathematical model presented considering effects force, geometric structure. This leads...

The no-slip boundary condition, i.e., zero fluid velocity relative to the solid at the fluid-solid interface, has been very successful in describing many macroscopic flows. A problem of principle arises when the no-slip boundary condition is used to model the hydrodynamics of immiscible-fluid displacement in the vicinity of the moving contact line, where the interface separating two immiscible ...

Deposition of colloidal particles in a porous medium is typically considered to be problematic energy and water applications. Here, experiments demonstrate that deposition can, surprisingly, promote mobilization trapped immiscible fluid from without requiring any surface activity. Analysis the underlying physics provides way predict characteristics mobilized as progresses.

The three-dimensional interfacial waves due to a fundamental singularity steadily moving in a system of two semi-infinite immiscible fluids of different densities are investigated analytically. The two fluids are assumed to be incompressible and homogenous. There are three systems to be considered: one with two inviscid fluids, one with an upper viscous and a lower inviscid fluid, and one with ...
