Electrokinetic transport of fluids through microchannel by micropumping and microperistaltic pumping has much interest for many engineering, medical, and industrial applications. Motivated in part by the need of mathematical model to study the electrokinetic transport by peristaltic pumping, an analytical approach is presented. A non-integral number of wave propagation is considered for transportation of fluid bolus along the channel length. Debye-Huckel linearization is employed to find out the potential function. A non-dimensional analysis is employed to simplify the governing equations. Low Reynolds number and large wavelength approximations are taken into account. The effects of characteristic electrical double layer (EDL) thickness and maximum electroosmotic velocity on pumping characteristics are discussed by computational results.
