Book Description
An analysis has been conducted to predict the liquid superheats that will be required to initiate nucleate boiling in the alkali metals. The classical two-phase mechanical and thermal equilibrium equation is solved by applying a modeling of the behavior of the pressure in the liquid for water and the alkali metals. Curves are presented showing the liquid superheats required for nucleate boiling in sodium and potassium.

Book Description
A survey was originated for the purpose of collecting and evaluating information pertaining to the current status of liquid-metal-boiling technology. Existing correlations for predicting heat-transfer coefficients in the nucleate- and film-boiling regimes are simmarized. Correlations which predict the critical heat flux are presented and compared with the experimental data available. The importance of two-phase-flow considerations in understanding the heat-transfer phenomena prompted the inclusion of additional sections regarding flow regimes and the pressure drops in flowing two-phase media. Appended is a summary of physical properties for various liquid metals and water.

Book Description
Nucleate boiling for sodium, rubidium, cesium, and water was studied. The critical heat fluxes were lower than hydrodynamic theory had predicted. Film boiling of potassium from a horizontal plate was studied. The flux level and the temperature difference between the surface and the fluid at the incipience of stable film boiling differed from earlier predictions. Agravic studies with pool boiling mercury were studied at accelerations up to 20 g's. Increases in pressure and acceleration usually improved the heat transfer. Sodium condensing studies resulted in coefficients of approximately 18,000 Btu/hr sq ft. for fluxes up to 500,000 Btu/hr sq ft. These are much lower than predictions from Nusselt's theory. Two phase flow potassium pressure drop, void fraction and heat transfer studies were conducted. Pressure drop studies yielded lower results than predicted by Lockart - Martinelli procedures. The void fraction studies agreed with Baroczy's predictions. The heat transfer studies were conducted at qualities up to 17%. (Author).
