摘　　要：在常压条件下对水平波槽管管外凝结换热及流阻特性进行了实验研究。实验结果表明,波槽管具有良好的强化传热效果。在实验参数范围内,波槽管的总传热系数比光管提高48%以上。通过对实验数据的回归分析,得到了管内对流换热、管外凝结换热及阻力系数的实验关联式。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.
