Electroosmotic velocity in an array of parallel cylindrical fibers with a slip surface

Abstract

A theory of electroosmosis in an array of parallel cylindrical fibers of Kozak and Davis (J Colloid Interface Sci 112:403–411, 1986) is extended to cover the case where the hydrodynamic slip occurs on the fiber surface. An analytic formula for the electroosmotic velocity for low zeta potentials is obtained, and its simple approximate expression without involving numerical integration is also derived.
