Stability of Liquid-Liquid Stratified Microchannel Flow under the Effects of Boundary Slip

Abstract

The effects of boundary slip on the stability of viscosity-stratified microchannel flow are investigated. In this approach, the boundary slip is considered by Navier slip assumption and the stability of the flow is studied by the small disturbance theory. Numerical results indicate that the stability of stratified microchannel flow is enhanced by boundary slip and it is controlled by boundary slip, the ratio of viscosity, surface tension and interface location.
