Principal Mechanism of Boiling Crisis in Pool Boiling

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1968
Abstract High-speed photography has been employed to study the mechanism of the boiling crisis in pool boiling of saturated water at high heat fluxes. Three configurations have been examined: normal free boiling on a heated 10-mm dia. horizontal copper disc and the same system subjected to the interference of a flat plate and a short tube held above ...

Pool Boiling Curve in Microgravity [PDF]

open access: yesJournal of Thermophysics and Heat Transfer, 1997
Pool boiling experiments using R-113 were conducted in the microgravity of space on a flat heater, consisting of a semitransparent gold film sputtered on quartz substrate, 19.05 x 38.1 mm (0.75 x 1.50 in.). Transient measurements of both the mean heater surface temperature and input heat flux are used to compute the mean heat transfer coefficient at ...
