On the dynamics of nucleate boiling

Nuclear Engineering and Design, 1972
Abstract A transfer function believed to describe the dynamics of pool boiling heat transfer was developed analytically. A feedback system for control of the heater surface temperature was then designed and very successfully operated. It thus became possible to experimentally test the validity of the analytical transfer function.

An onset of nucleate boiling criterion for horizontal flow boiling

International Journal of Thermal Sciences, 2000
An extensive database has been collected for the evaporation of two hydrofluorocarbon refrigerants (HFC- 134a and the zeotropic mixture HFC- 407C) and the natural refrigerant ammonia (R-717). A model to predict the onset of nucleate boiling has been successfully developed to differentiate pure convective evaporation from mixed convective and nucleate ...

Surface Nanobubbles Nucleate Liquid Boiling

Langmuir, 2018
Surface nanobubbles have been presumed to lead to the experimental observation that liquid boiling often occurs at a much lower supersaturation than expected, yet no qualitative theory exists to explain how they participate in the process. Here, we report through a simple theoretical analysis on how the metastable nanobubbles nucleate the liquid-to ...

Nucleation of boiling and cavitation

Journal of Physics D: Applied Physics, 1977
A number of measurements of the conditions required to nucleate boiling and cavitation in stagnant water are described, and used to test theories of nucleation by surface cavities. For given conditions prior to nucleation the concept of a constant cavity radius appears valid.

Onset of nucleate boiling in minichannels

International Journal of Thermal Sciences, 2000
Abstract Heat transfer characteristics during flow boiling in a minichannel were studied. For these investigations a thermographic measuring method was used. The axial distribution of the external wall temperature was measured, from which the internal wall temperatures and the local heat transfer coefficient are calculable.

Effect of pressure on boiling nucleation

Journal of Physics D: Applied Physics, 1983
It is shown experimentally that a previously imposed deactivating pressure can render nucleation of subsequent boiling much more difficult. The results provide strong support for an analysis of the way that the liquid-vapour interface behaves within surface cavities.
