Peristaltic motion of two immiscible viscous incompressible fluids in a circular tube is studied in pumping and copumping ranges under long-wavelength and low-Reynolds-number assumptions. The effect of the peripheral-layer viscosity on the time-averaged flux and the mechanical efficiency is studied. ...
Couette flow of two viscous, incompressible, immiscible fluids in a channel bounded by permeable beds is investigated. The lower bed is of finite thickness with high permeability and the upper bed is of infinite thickness with low permeability. The flow in the lower permeable bed is described by...
Abstract A local analysis has been made about a point at the free surface of an incompressible viscous fluid flow at steady state by means of series expans... HJ Lugt - 《Physics of Fluids》 被引量: 61发表: 1987年 Exchange flow of two immiscible fluids and the principle of maximum flux...
The notion of varifold solutions for the free boundary problem associated with the flow of two immiscible incompressible viscous fluids with surface tension has been introduced by Abels [2]. For Newtonian fluids, the global-in-time existence of such varifold solutions has been proven for quite ...

We study experimentally the parallel flow in a Hele–Shaw cell of two immiscible fluids, a gas and a viscous liquid, driven by a given pressure gradient. W... P Gondret,M Rabaud - 《Physics of Fluids》 被引量: 119发表: 1997年 Stability of Two-Layer Fluid Flow in AN Inclined Channel...
The present paper deals with the study of Kevin-Helmholtz instability in a porous medium using viscous potential flow theory. Both fluids are taken as incompressible and viscous with different kinematic viscosities. A dispersion relation has been obtained and stability criterion is given by a critical...
3 . 2.4 definition of varifold and strong solutions in this subsection, we present definitions of strong and varifold solutions for the free-boundary problem of the evolution of two immiscible, incompressible, viscous fluids separated by a sharp interface with surface tension inside a bounded domain...
The model describes flow of two incompressible and immiscible fluids (\(\text {w}\) and \(\text {n}\)) in a porous medium. The porous medium is represented by a network consisting of N nodes that are connected by M links. The nodes are each given an index \(i \in \left[ 0, ...
Consider two superposed layers of two incompressible, viscous fluids over a flat plate that coincides with the x-z plane of the Cartesian co-ordinate system . The y-axis is the coordinate normal to the plate. Both of the two fluids that form the layers are Newtonian. The fluids are of di...
