A model is proposed for the heat-transfer process associated with nucleate boiling. The authors discuss and analyze the various heat-flux components from the heating surface due to: evaporation of the liquid microlayer under a bubble; heating of the liquid that displaces the detached bubble; and convection on the parts of the surface outside the bubble-wall contact zone. The resultant heat flux is expressed as the sum of the local heat fluxes averaged over time and space. The relations obtained for calculation of the heat-transfer coefficient of nucleate boiling satisfactorily describe the experimental data for fully developed boiling of alkali metals and ordinary liquids.
