Fully Developed Hydrodynamic and Thermal Transport of Combined Pressure and Electrokinetically-driven Flow in a Microchannel With Three Immiscible Fluids

Abstract

Thermally and hydrodynamically fully developed combined pressure-driven and electroosmotic flow through a channel with three immiscible fluids has been simulated for isoflux wall boundary conditions. Closed form expressions have been developed for velocity and temperature profiles and Nusselt number. The results indicate strong effects of fluid layer thickness, force fields and boundary conditions.
