- Abstract
- In this paper, we have performed a parametric study on the characteristics of multiphase laminar flow with
density difference in various microchannels. The interface between multiphase fluids is rotated by the
gravitational forces induced by density difference. The numerical simulations were carried out via commercial
CFD package to study the characteristics of multiphase laminar flow. The results of the numerical simulations
in this study were verified by comparing with the previously reported experimental results in the literature.
We have also proposed a new dimensionless relationship between dimensionless rotation angle of interface
and dimensionless parameters are proposed for square microchannels with various aspect ratios. The
dimensionless relationship could be widely applied to the reliable design of various microfluidic devices
dealing with multiphase laminar flow.
