Abstract: The process of electroosmotic flow in a slit microchannel which thickness of an order of several EDL is investigated. The model and derived solutions allow to predict velocity profiles and time of the steady state flow development in cases of both altering and current external electric field. Analytical solutions for spatial EDL potential distribution and velocity are obtained. The results of the simulation are in a good agreement with the experimental data
