Electrohydrodynamic Enforcement in the Heat and Mass Exchange

摘要

The net drag effect of the ionic current in the conductive fluid, electrohydrodynamic (EHD) effect, has been investigated as a space and energy saving technology for the enforced heat and mass management. The electrodynamically enforced evaporation, convection and closed-loop phase-change thermal transfer are analyzed and experimentally evaluated. The emphasis of the investigation was on the maximal efficiency of the consumed power. Significance of EHD phenomena for the energy saving is demonstrated on the examples of temperature stabilization for the solid state lighting and the dewatering of the pulp in the paper industry.
