Abstract

An electroosmotic pumping flow model of aqueous electrolytes confined in a microchannel with squeezing walls is developed in this study. The mathematical model is derived based on using a strong coupling between the nonlinear Poisson–Boltzmann equation and the flow lubrication theory. The model aims to study electrolyte creeping flow transport in a microchannel and to describe the distribution of the electric potential across the electric double layer. The effects of wall zeta potential on the fluid axial velocity profiles and time-averaged net flow rate are presented. The results show that the electrokinetics parameters can be used to alter the net flow directionality without any additional mechanical valves and this system can work as a micropump.
