摘要

This paper presents the experimental investigation of pool boiling heat transfer performance of copper plain and grooved horizontal circular surfaces immersed in saturated water at atmospheric pressure. The effect of the geometric parameters of the groove on boiling heat transfer was studied. From the experimental results, it was observed that the enhanced surfaces have a positive effect on the heat dissipation and the effect is greater than in the case of a plain surface. It was found that the heat dissipation increases with increasing groove depth, decreasing groove angle, and decreasing channel width. The improved heat transfer is attributed to improved bubble dynamics, which are a function of the heat transfer area, bubble escape resistance, and capillary force. The dominance of any of these factors over the other depends on a particular specimen. The modified Rohsenow correlation predicts the present experimental data with an error of +/- 20%.
