Abstract

This paper presents the results of experimental studies of cooling a zirconium ball in subcooled ethanol under the action of a submerged jet. The degree of subcooling of the cooled liquid and the distance from the nozzle exit to the cooled surface varies during the experiments. The heat patterns of cooling are presented and the effect of the distance between the nozzle and the surface on the duration of cooling and the transition temperature from stable film boiling to intense heat transfer is revealed.
