RT Journal Article ID 7805037c5ba140ff A1 Benhamza, M-ed El Hocine A1 Chouarfa, Fella T1 Validity of Solid-Liquid Bubble Interface Modeling in Partial Nucleate Boiling JF Heat Transfer Research JO HTR YR 2009 FD 2009-11-13 VO 40 IS 8 SP 793 OP 804 K1 boiling heat transfer models; nucleate boiling; contact angle K1 nucleation-site density AB In this study, an identification of various models of partial nucleate boiling heat transfer is carried out in order to recognize the dependence between dominant physical parameters. There is a multitude of correlations for modeling nucleate boiling heat transfer phenomena, so the main goal of this analysis is to determine the validity of each model and at the same time to identify the more dominating nucleate boiling heat transfer physical phenomenon. This is done by comparing different models with a vast range of reliable experimental data. Comparison between various correlations and experimental data shows that the Sakashita and Kumada model gives the best results in nucleate boiling heat transfer. Results also show that the most dominating physical phenomenon in the zones of partially isolated bubbles is transient conduction, taking place mainly under the bubbles. This is in contrast with the majority of the models which consider convection as the most important mode in nucleate boiling heat transfer. An increase in the nucleation-site density leads to a decrease in the size of activation cavities as well as in a detachment diameter of vapor bubbles. The selected model can also be extrapolated and used in the case of fully developed bubble zones.
