Abstract

"An experimental investigation was performed to study the nucleate pool boiling heat transfer from a 3-in. long vertical cylinder rotating in liquid nitrogen at atmospheric pressure. The 1-in. diameter copper cylinder with internal heater was rotated at speeds of 175, 350, 500, and 695 rpm. A uniform heat transfer surface was created by peening the cylinder with glass beads.

From 0 to approximately 3,000 Btu/hr-ft 2, the wall temperature of the rotating cylinder differed little from that obtained in the non-rotating case. From approximately 4,000 to 10,000 Btu/hr-ft 2, the wall temperature of the rotating cylinder decreased, as the heat flux was increased, to values below the bulk liquid temperature. Also, for a given heat flux, the wall temperature decreased as the speed of rotation was increased. A minimum value of wall temperature occurred at a heat flux of approximately 10,000 Btu/hr-ft 2, for all rotational speeds. From approximately 10,000 Btu/hr-ft 2 to the critical heat flux of 14,500 Btu/ hr-ft 2, the wall temperature increased as the heat flux was increased. Although the wall temperature continued to increase throughout this region, at burnout the wall temperature was below that obtained for the stationary cylinder at burnout.

The data was correlated with a modified form of the Rohsenow correlation "--Abstract, page ii
