An experiment on nucleate pool boiling heat transfer from horizontal cylinders to saturated, distilled water under atmospheric pressure is reported. Experiments of nucleate pool boiling were conducted using stainless steel tubes with OD: 8.15 mm and 18.04 mm and active length about 250 mm. In particular, measurements have been performed of inside circumferential temperature. Three component model of nucleate pool boiling outside horizontal tube has been proposed. The proposed mechanisms of heat transfer that have contribution in total heat flux are: free convection, evaporation to sliding bubbles and nucleate boiling.
