Study of Electro-osmotic flow in microfluidic devices

Abstract

Several fluid movement techniques in microchannel have been introduced in the past, the most recent technique is by applying an electric field to a fluid enclosed between capillary surfaces. This technique is called electrokinetically driven flow. The modeling and simulation of electrokinetic transports of fluid in various typical micro-channel geometries such as T-channel, L-channel, and curved channel were done in this paper using commercial simulation software Coventorwarereg. The study has focused on finding the effects of electroosmotic forces on the micro-scale flow fields, and flow control of electroosmotic flow in micro-geometries including the dispersion of liquid flow in the micro channels of different geometries.
