| Abstract: | The experimental study is discussed in this paper for the heat transfer and pressure drop of a new type enhanced tube-the "W" type spirally corrugated tubes,and its mechanism and feature of augmentation heat transfer is described.The results of the study show that the total heat transfer coefficient of the "W" type spirally corrugated tube is 17% higher than that of the smooth tube.Correlations for the pressure drop and heat transfer coefficient of heat exchangers were obtained. |
