  • Effect of Micro Honeycomb Porous Plate on the Critical Heat Flux in Saturated Pool Boiling

説明

<p>Enhancement of the critical heat flux in pool boiling by the attachment of a micro HPP on a heated surface is investigated experimentally using water under saturated boiling conditions. HPP enhance the CHF from the capillary supply of liquid onto the heated surface through the pores and the release of vapor generated through the channels. When the height of the micro HPP on the heated surface is 1.4 mm, the CHF increases to 2.5 MW/m2. While the CHF began to decrease when the thickness was more than1.4 mm. In regions of thin HPP thickness, the CHF can be explained by the Haramura-Katto model. Therefore, in this presentation we examined the CHF mechanism in the thicker HPP region using the capillary limit model.</p>
