A heat transfer coefficient (HTC) model was developed for the prediction of post-boiling transition (post-BT) behavior that might occur during anticipated operational occurrences (AOOs) for boiling water reactors (BWRs). The model development was based on measurements of heat transfer coefficient, liquid droplet deposition rate, and droplet concentration in our experiments conducted at high pressure. The model focused on the heat transfer near the rewetting front where the cooling by droplet deposition significantly affects the propagation behavior of a liquid film. The correlation by Sugawara was validated for the prediction of the deposition by using the experimental data. The model was also expressed as a function of the distance from the rewetting front to use in analytical models for the rewetting propagation. Both expressions of the present model successfully predicted our experimental data simulating the BWR thermal-hydraulic conditions.

“…14 The relationship of the local Sherwood number to the Sherwood number for a fully developed concentration profile is deduced by analogy with heat transfer from Sparrow's expression for the ratio Nu x /Nu m . Sparrow, Hallman, and Siegel considered the problem of turbulent heat transfer in the thermal entrance region of a pipe with uniform heat flux, 16 which is analogous to the case of turbulent mass transfer in the concentration entrance region of a pipe with uniform low mass flux. The expression which they obtained is:…”
