Principal Mechanism of Boiling Crisis in Pool Boiling

Transactions 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 ...
