Abstract

Abstract

Investigation of heat transfer and friction characteristics had been conducted at atmosphere pressure on B30 horizontal circularly-grooved tube.The experimental result indicates that the circularly-grooved tube can effectively enhance the heat transfer.Within the experimental scope,the total heat transfer coefficient of the circularly-grooved tube can be increased more than 48% compared with that of the smooth tube.Through regression analysis on the experimental data,the experimental correlations for the inside heat transfer coefficient,the condensation heat transfer coefficient on film condensation and the friction coefficient were achieved.
