Numerical simulation of two-fluid electroosmotic flow in microchannels. (English) Zbl 1188.76278
Summary: This paper presents a numerical scheme for stratified two-liquid electroosmotic flows. The simulation results highlight that using the electroosmotic effects can control the interface location of a pressure-driven two-liquid flow. A finite volume method is used to solve the coupled electric potential equation and Navier-Stokes equation together.
The validity of the numerical scheme is evaluated by comparing its predictions with the results of the analytical solutions in the fully developed regions. The liquid-liquid interface developments due to the favorably and adversely applied electric field are examined.
