The total osmotic flow of water across cell membranes generally exceeds diffusional flow measured with labeled water. The ratio of osmotic to diffusional flow has been widely used as a basis for the calculation of the radius of pores in the membrane, assuming Poiseuille flow of water through the pores. An important assumption underlying this calculation is that both osmotic and diffusional flow...

In this study a novel mathematical model for electroosmotic flow Cu-water based nanofluid with heat transfer phenomenon is reported scraped-surface exchanger. The initiated due to motion of lower wall the channel and axial pressure gradient. modelled aid low Reynolds number lubrication approximation theory. Exact analytical expressions are gathered velocity, stream functions various stations Ph...

A fundamental electrokinetic phenomenon is the electro-osmotic flow of a liquid electrolyte (solution of positive and negative ions) past a charged surface in response to a tangential electric field. Electrophoresis is the related phenomenon of motion of a colloidal particle or molecule in a background electric field, propelled by electro-osmotic flow in the opposite direction. The basic physic...

The present experiments were designed to evaluate coupling of water and nonelectrolyte flows in porous lipid bilayer membranes (i.e., in the presence of amphotericin B) in series with unstirred layers. Alterations in solute flux during osmosis, with respect to the flux in the absence of net water flow, could be related to two factors: first, changes in the diffusional component of solute flux r...

The net flow of electrolyte induced by an ac electric potential applied to an array of asymmetric pairs of microelectrodes has recently been reported. The interaction between the oscillating electric field and the oscillating induced charge at the diffuse double layer on the electrodes results in a steady electro-osmotic velocity distribution on top of the electrodes. This slip velocity distrib...
