ANALYTICAL SOLUTION OF THE FLOW ALONG PARALLEL MICROCHANNELS SEPARATED BY A POROUS MEMBRANE

摘要

This papers presents the analytical solution of the flow distribution along a porous membrane which is between two parallel microchannels, a configuration of increasing importance in microsystems for DNA sequencing, catalytic chemistry, and in micro heat exchangers. The modeling approach presented in the paper is inspired from thin film lubrication theory and would be applicable for a wide range of low Reynolds number, pressure-driven microfluidic configurations.
