Abstract: A fundamental understanding of the transport phenomena in microfluidic channels is critical for systematic design and precise control of such miniaturized devices towards the integration and automation of Lab-on- a-chip devices. Electroosmotic flow is widely used to transport and mix fluids in microfluidic systems. Electroosmotic transport in convergent divergent micronozzle is significant in many applications, such as biomolecular transport, DNA transport in cell patch clamps. The goal of this paper is to develop a theoretical model of electroosmotic flow in micronozzle to gain a better understanding of transport phenomena in microfluidics channels. Numerical study of electroosmotic flow through convergent divergent nozzle microchannels has been developed in this paper. The governing equations consist of a 2D Poisson-Boltzman equation and a 2D Navier-Stoke's equation with Electric Double Layer(EDL) field. The potential distribution of the EDL in the channel is ob!
tained by solving the non-linear 2D Poisson–Blotzmann equation using finite element technique. Then the solution for the 2D Navier-Stoke's equation for the velocity distribution is also obtained. The velocity distribution profiles are obtained using COMSOL Multiphysics software.
