Abstract

Electrohydrodynamic (EHD) enhancement of pool boiling may improve heat-sinks used in micro-electronic devices. The effect depends on the applied electrode voltage. Mathematical models for the heat transfer coefficient with refrigerant R11 for boiling in both free convection and nucleate regions are developed from experimental results. The results show that heat removal is enhanced by 250 percent in the free convection region, and by a lesser amount in the nucleate region.
