Abstract: Horizontal plane heating surface with 3 kinds of different screw diameter was installed in order to obtain enhancement of saturated pool nucleate boiling heat transfer. The knowledge and findings obtained through this experiment are the following. The interstice between the screwed heating surface and the screw division was found to supply the bubble nucleus, and heat transfer coefficient was enhanced up to 3.2 times in comparison with the heating surface with the screw and without the screw in concentric circle. Heat transfer coefficient also increased with the screw diameter and with the decrease in the pressure. Within the range of experimental conditions, a dimensionless correlation for the saturated pool nucleate boiling heat transfer at the heating surface with the screw in the concentric circle was obtained.
