INVESTIGATION OF LIQUID METAL BOILING HEAT TRANSFER
Abstract
Pool boiling data has been obtained for potassium from the outside of a 7/8-in diameter bayonet tube. Boiling curves were determined at pressures up to 45 psia and burnout measurements were taken for pressures up to 20 psia. The burnout flux at 1 atm. was 610,000 Btu/(hr) (sq ft) and showed less pressure dependence than predicted by the relationships of Noyes, Zuber-Tribus, and Kutateladze. Operation of the film boiler has been delayed by leaks in the environmental chamber surrounding the boiling system. Edge effects cannot be evaluated in the apparatus because of the 400 F limitation on the columbium when operating with water. The con denser, which dissipates heat by radiation, is flooded at these lower temperatures. Startup difficulties with the loop have persisted and attempts to eliminate a plugging problem in the pump restriction are continuing. Prior to plugging, the loop and associated instrumentation was all functioning normally.
