Paper Abstract

A study of pressure-driven liquid flow in microchannels is presented with the aim of providing a simple model for microfluidics. The paper presents the initial research effort, which covers a survey of CFD packages, the general principles for fluid dynamics, and a simple model of flow in microchannels formulated from these governing equations. The model demonstrates how the capillary force affects the flow and the applicability of boundary layer theory to the flow in a microchannel. The simulation of textures in a microchannel, and difficulties in modelling, are then discussed.
