Numerical Simulation on Electro-Osmotic-Flow in Microchannel

The drive mode of fluid body in microchannel is a key in microfluidic control system. ElectroOsmotic MicroPump (EOP) is a microfluidic system which is controlled by electric field with no moving parts. EOPs are attracting increasing attention due to the ease of fluid control in complex microchannels. The theory of forming Electro-Osmotic-Flow (EOF) is analyzed and governing equations are given based on the mechanism forming EOF. After analyzing and simplifying governing equations, numerical simulation of those equations is performed by finite difference method and vorticity-stream function. Simulation results interpret the relations between parameters, which offer the foundation to research EOP.
