Abstract

A model of electrolyte flow in porous media is proposed. Within the bounds of this model the analytical dependence of filtration flow rate on pore-metric curve, zeta potential of matrix solid material and electrolyte concentration is obtained. The results of calculations are in qualitative agreement with experimental data concerning influence of listed above factors on fluid flow in microchannels. Determined that in presence of sufficient amount of channels with radius comparable with EDL thickness the filtration velocity greatly decreases as against the velocity obtained without taking into account electrokinetic effects, and in cases of high electrolyte concentration the filtration velocity practically not differs from velocity predicted by conventional theory (D'Arcy law).
