Abstract

Enhanced heat transfer via boiling in a porous layer covering the heated surface is considered analytically. The effect of vapor channels traversing the porous layer on the power for which a vapor film on the heated surface occurs, is examined by comparing the heat removal capability of the system with and without channels. A significant increase of the attained coolability level is obtained theoretically leading to the possibility of new design configurations for the cooling of intensely heated surfaces.
