Electro-osmotic pumping of sodium chloride solutions
Electro-osmotic pumping (EOP) theory and its characteristics (transport numbers, brine concentration, current density, current efficiency, electro-osmotic coefficients, etc.) of Selemion AMV and CMV ion-exchange membranes were studied. The brine concentration increased with increase in current density and feed water concentration. Current efficiency was nearly constant in a wide range of curren...
متن کاملTransient Electro-Oosmotic Pumping in Rectangular Microchannels
Two-dimensional Poisson-Boltzmann and momentum equations are solved simultaneously to study the transient characteristics of electro-osmotic pumping in a rectangular microchannel. A finite difference scheme with variable grid spacing is used to calculate electric potential distribution. Time variations of velocity profiles are obtained by using a combined ADI-TDMA technique. Numerical solutions...
متن کاملElectro-osmotic Flow Through a Rotating Microchannel
An analytical model is presented for electro-osmotic flow through a wide rectangular microchannel rotating about an axis perpendicular to its own. The flow is driven by a steady electric field applied along the channel axis, where the upper and lower walls are charged with uniform but possibly disparate zeta potentials. The aim is to understand the interaction between Coriolis force, pressure g...
متن کاملElectro-osmotic propulsion of helical nanobelt swimmers
Micro and nanoscale mobile agents capable of self-propulsion in low Reynolds number fluids would have a great technological impact in many fields. Few known mechanisms are able to propel such devices. Here we describe helical nanobelt (HNB) swimmers actuated by an electric field-generated electro-osmotic force. These HNB swimmers are designed with a head and a tail, similar to natural micro-org...
متن کاملElectro-osmotic flow of semidilute polyelectrolyte solutions.
We investigate electro-osmosis in aqueous solutions of polyelectrolytes using mean-field equations. A solution of positively charged polyelectrolytes is confined between two negatively charged planar surfaces, and an electric field is applied parallel to the surfaces. When electrostatic attraction between the polymer and the surface is strong, the polymers adhere to the surface, forming a highl...
