Effect of steam content and a pressure pulse on nonstationary heat transfer during film boiling
The study of nonstationary heat transfer during cooling of metallic spheres submerged in the coolant is stimulated, to a significant degree by nuclear power plant safety. For example, for computational analysis of the intense energy interaction (steam explosion) arising when melt from the core enters the coolant, it is necessary to known the heat transfer coefficients from the melt fragments to the coolant, which can be either a liquid or a steam-vapor mixture. For underheated and saturated liquid, there exist experimental data and recommendations for calculating the heat transfer coefficients during film boiling on spheres, whereas for conditions of cooling in a vapor-water mixture there are no such data.
