Forster-Zuber

The starting point for the Forster-Zuber theory (F4, F5, F6) is the Rayleigh equation (Rl) for a bubble growing in a liquid medium. In this... 

The temperature of a bubble growing in a superheated liquid changes with the bubble size. If liquid inertia is negligible, the Forster-Zuber derivation gives the expression... 

Verification of the Forster-Zuber formulas has been of two kinds, checks of Eq. (15) and of Eq. (21). Ellion (El) conducted a photographic study to determine the rate of growth of bubbles of steam and of carbon... 

Fio. 14. The Forster-Zuber correlation for nucleate boiling of four liquids. Only data near the critical AT are represented (F6). 

A test of Eq. (21), or (20), is shown in Fig. 14. The same maximum heat-flux data of Cichelli and Bonilla (C2) for three organic liquids which produced three separate lines by Rohsenow s correlation give a single line on the Forster-Zuber plot. The data of Kazakova (Kl) for water boiling at pressures varying from 10 to 80% of the critical pressure also fit the line nicely. 

Question by J. A. Clark, University of Michigan I believe the Forster—Zuber correlation is for the maximum heat flux points. How is this correlation justified for application to the nucleate-boiling data Did you correlate the peak flux data with any of the existing correlations ... 

Answer by Author It is our understanding that the Forster—Zuber correlation applies also to the entire nucleate-boiling curve. No correlation was attempted with the peak flux data since our peak flux data are slightly lower than a true peak, and we were not primarily concerned with locating this point.
