Experimental determination of the induction period for the onset of intensive boiling of a subcooled water flow under conditions of unsteady heat release [PDF]
E3S Web of Conferences, 2019 This paper studies prediction of the boiling crisis onset under conditions of the rapid temperature growth of the heat releasing surface washed by a water flow subcooled to the saturation temperature. We obtained experimental data on time delay for rapid

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 ...
