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.
