抄録

Nucleate boiling heat transfer characteristics for a tube in a bundle differ from those for a single tube in a pool and this difference is known as tube bundle effect. There exist two bundle effects, positive and negative. The positive bundle effect enhances heat transfer due to convective flow induced by rising bubbles generated from the lower tubes, while the negative bundle effect deteriorates heat transfer due to vapor blanketing caused by accumulation of bubbles. In this study, experiments are performed in detail by using bundles of small scale, and effects of heat flux distribution, pressure and tube location are clarified. Furthermore, some consideration on the mechanisms of occurrence of 'tube bundle effect' are given and a method for prediction of heat transfer rate is proposed.
