BOILING HEAT TRANSFER CHARACTERISTICS WITH HIGH MASS FLUX AND DISAPPEARANCE OF CHF FOLLOWING TO DNB
要約
This paper presents complete boiling heat transfer characteristics of highly subcooled Freon-113 flowing with a very high mass flux. It is well kown that the CHF phenomenon following to DNB is characterized by a sharp reduction of heat transfer coefficient because of the transition of heat transfer mechanism from nucleate to film boiling. But it can be eliminated with the combined effects of high mass flux and subcooling, if the heat transfer ability of film boiling is enhanced equal to that of nucleate boiling at the CHF condition.
