Study of Boiling Characteristic Curves in Subcooled Pool Boiling of Water (4th Report, The Mechanism of Heat Transfer in Transition Boiling)

Pool Boiling Heat Transfer in Water/Amines Solutions

In this investigation, nucleate boiling heat transfer coefficients were experimentally measured during pool boiling of mixtures, consisting of water/monoethanolamine and water/diethanolamine on a horizontal heating rod, under atmospheric pressure. The experiment was carried out below 205 kW.m-2 heat flux, over a wide range of concentrations. These experiments include, measurement of pool boilin...

Experimental Study for Investigating the Mechanism of Heat Transfer near the Critical Heat Flux in Nucleate Pool Boiling

Heat transfer coefficient in nucleate pool boiling near critical heat flux at least one orderhigher than the convectional heat transfer modes. In this paper, an experimental setup isdesigned and fabricated to investigate the mechanism of heat transfer from boiling surface tobulk liquid near critical heat flux. The images of pool boiling near the high heat flux regionreveals that the individual ...

Highly subcooled pool boiling heat transfer at various gravity levels

A microscale heater array 2:7 mm 2:7 mm in size along with a video camera was used to provide subcooled pool boiling heat transfer measurements at gravity levels ranging from 1.8g to 10 g. The fluid was FC-72 at 1 atm and subcooled by nominally 36 C for all cases. A Terrier–Orion sounding rocket and the KC-135 aircraft were used to provide the microgravity and low-g environments, respectively. ...

Experimental Investigation in Pool Boiling Heat Transfer of Pure/Binary Mixtures and Heat Transfer Correlations

Nucleate pool boiling heat transfer coefficient have been experimentally measured on a horizontal rod heater for various liquid binary mixtures. Measurements are based on more than three hundred data points on a wide range of concentrations and heat fluxes. In this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in p...
