摘要：

An electrokinetic model for microfluidic flow has been developed. The effects of surface waviness of the channel wall on a pressure-driven flow have been investigated. Current analysis considers a cylindrical microchannel of finite length, having two reservoirs at ends. Poisson-Nemst-Planck and Navier-Stokes equations constitute the electrokinetic model. Significant influence of the concentration boundary condition, at the reservoir exit plane, on the solution was observed. Solvent flux and channel length are two determining factors for the concentration distribution along the channel length. The effects of frequency and amplitude of the surface waviness were also investigated. Any irregularity in channel wall causes higher concentration and potential gradients across the channel.
