Abstract:In this paper, we first present successful modeling and analysis results of a centrifugal force driven transient filling flow into a rectangular microchannel. Two types of exact and pseudo-static approximate solutions were derived for the transient filling flow. The analytic solutions include expressions for flow front advancement, detailed velocity profile and pressure distribution. The obtained analytical results show that the filling flow driven by centrifugal force is affected by three dimensionless parameters which combine fluid properties, rectangular channel geometry and processing condition of rotational speed. We also first provide a simple analytical design tool for a rectangular microchannel based on the modeling and analysis in this study.
