NUMERICAL SIMULATION OF THE LIQUID EXTRACTION FROM A STRATIFIED LIQUID-VAPOR ZONE USING ELECTROHYDRODYNAMIC EFFECTS

A quasi-steady numerical methodology was developed to predict the liquid extraction from a stratified liquid-vapor zone due to electrohydrodynamics (EHD). The stratified liquid-vapor was in a tube, and a step DC voltage was applied using a central electrode along the tube axis. The solution for the electric field was coupled with the Navier-Stokes equations to determine the interfacial velocities. Here, the electric field imposes an interfacial …
