A model for the dispersed droplet post-dryout regime has been developed by considering nonequilibrium heat transfer between the vapor and the liquid droplets. The analysis has resulted in two correlations for the volumetric mass rate of vapor generation. The first correlation is based on the effectiveness of vapor-to-droplet heat transfer, and the second is based on the droplet size. Both the correlations, used with the Heineman correlation for superheated steam, are successful in predicting the wall temperatures in steam-water round tube systems (6–15 mm ID) for a wide range of pressures (29–120 bar), mass fluxes (393–2590 kg/m² s), equilibrium qualities (0.17–1.50) and wall superheats (167–556°C).
