A new microstructure for pool boiling
Superlattices and Microstructures, 2004Abstract Combining electrocoating and etching processes, we have developed a new type of microstructure for nucleate boiling. The basic elements of the structure are cylindrically shaped; their density ranges up to 107 cm−2. To test the efficiency of the structure, the outer surface of a tube has been provided with such a structure and used in pool ...

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

Burnout in pool boiling the stability of boiling mechanisms
International Journal of Heat and Mass Transfer, 1972Abstract In pool boiling, when the burnout heat flux is approached, a large number of areas are observed where the heating surface is dry for short intervals. The mechanism of formation of these dry areas is different for atmosphere and low-pressure conditions. The majority of dry areas do not lead to burnout.

On the pool height for transient pool boil-up
Chemical Engineering Science, 1986Abstract The height of a pool undergoing transient, bulk boiling is determined analytically. The results generalize existing theories by accounting for mass flow through the vessel floor and changing power supply, and delineate a term which describes the influence of vapour escape through the interface; the latter term quantifies the ultimate ...

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.

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.
