Nucleation site interaction during boiling
International Journal of Heat and Mass Transfer, 2000Abstract Classical analyses of boiling nucleation employ a linear approach with investigation focusing on a single site and the heat transfer obtained from the active site density assuming uniform wall superheat. This paper uses synergetic concepts and the self-organizing effect to analyze the interactions among active sites or bubbles induced by non-

Mechanism study of departure of nucleate boiling on forced convective channel flow boiling
International Journal of Heat and Mass Transfer, 2018We carried out a visualization study of Departure from Nucleate Boiling (DNB) of a vertical upward flow boiling condition. In order to evaluate the effects of the convective flow condition on the DNB mechanism, we synchronized three high-speed cameras ...

The first documented mention of superheated liquid occurred in 1777 when the London Royal Society issued a recommendation to place a thermometer bulb not in boiling water itself, but rather in its vapors. In 1873, a century later, Gibbs [1] was first to carry out a physical analysis of specific features of the superheated (“metastable”) state of liquid.

Enhanced nucleate pool boiling on copper-diamond textured surfaces
Applied Thermal Engineering, 2019This work describes an experimental investigation of enhanced nucleate pool boiling of water on textured surfaces. The textured surfaces are formed atop thin Copper-Diamond composite layers deposited by the Cold Spray manufacturing technique.

The process of evaporation associated with vapor bubbles in a liquid is called nucleate boiling. Here attention will be focused on boiling at heated solid surfaces of interest in engineering applications.

Flow boiling—the ‘apparently nucleate’ regime
International Journal of Heat and Mass Transfer, 1989This paper re-examines the nucleate boiling term in the Chen correlation (ASME Paper 63-HT-34 (1963)) for the heat transfer coefficient in flow boiling, which he derived from a correlation then current for pool boiling. The re-examination employs all available data published for water, with results of a recent simplified analysis of pool boiling which ...

Suction nucleate boiling of water
AIChE Journal, 1965AbstractSuction nucleate boiling (consisting of saturated pool boiling on a porous heat source with the generated vapor exhausting through the pores) was investigated experimentally and theoretically. The experimental results demonstrated that: (1) interfacial free energy can be used to direct the flow of liquid and vapor in a desired direction and to ...

Falling film evaporation and nucleate pool boiling heat transfer of R134a on the same enhanced tube
Applied Thermal Engineering, 2019Falling film evaporation and pool boiling of R134a outside a typical reentrant enhanced tube was investigated with an experimental approach. Experimental data from literature with other refrigerants were also compared.
