PHOTOGRAPHICAL STUDY FOR BOILING HEAT TRANSFER MECHANISM
摘要
Boiling heat transfer mechanism has been studied by using the electro-conductive glass plate and the photographical apparatus concerning to the bubble behavior on the heating surface. Series of experiments has been proceeded at atmospheric pressure using both electrically heated glass with or without the coating silicone in natural circulation and in forced circulation.
And variable combination of three main mechanism of boiling heat transfer, which are natural convective heat transmission caused by bubbling, unsteady heat transfer in case of bubble detachment and heat conduction in contact area of bubbles, were found.
