Onset of Nucleate Boiling and Active Nucleation Site Density During Subcooled Flow Boiling
Journal of Heat Transfer, 2002The partitioning of the heat flux supplied at the wall is one of the key issues that needs to be resolved if one is to model subcooled flow boiling accurately. The first step in studying wall heat flux partitioning is to account for the various heat transfer mechanisms involved and to know the location at which the onset of nucleate boiling (ONB ...

Nucleation Kinetics for Boiling in Microstructures
Heat Transfer: Volume 2, 2005Theoretical investigation is conducted to understand the bubble nucleation process in microstructures. The bubble evolution in microstructures is investigated for momentum conservation, and the evolution rate is deeply dependent on the structure. According to different dynamic characteristics in the region close to the critical radius, the nucleation ...

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.

Suppression of Flow Boiling Nucleation
Journal of Heat Transfer, 1997A simple model is presented for estimating the ratio of the maximum to minimum cavity radius required for ebullition in two-phase flow with heat transfer. The resulting dimensionless parameter, rmax/rmin, is demonstrated to correlate flow boiling nucleation site density.

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 ...

On the Hydrodynamic Transitions in Nucleate Boiling
Journal of Heat Transfer, 1963The two hydrodynamic transitions which take place in nucleate boiling off a horizontal surface are described. The first, which is governed by continuity considerations, results in a change in the vapor removal process from an intermittent to a continuous one.

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.

Investigation of chemical nucleate boiling
Journal of Engineering Physics, 1987The effect of the solution viscosity and particle size on chemical boiling kinetics is established. A quantitative estimate is obtained for chemical nucleate boiling under conditions of free convection.

The microlayer in nucleate pool boiling
International Journal of Heat and Mass Transfer, 1969Abstract Experiments are reported in which organic liquids underwent pool boiling at low pressure, forming large vapour bubbles on the surface of a heater plate consisting of glass or ceramic. The temperature at the surface of the heater was measured, leading to support for the hypothesis that a thin layer of liquid (the microlayer) forms beneath the
