The maximum heat flux may be predicted by the Kutateladse-Zuber [Trans. Am. Soc. Mech. Eng., 80, 711 (1958)] relationship, using consistent units ... 

In 1972, Vogtle and Zuber condensed 1,2-dibromomethylbenzene (xylylene dibromide) with another xylylene unit, 1,2-dihydroxymethylbenzene. The result was formation of the macrocyclic tetraether (40% yield, mp 194°) shown in Eq. (3.19). The...

FORSTER and ZUBER(85,86J who employed a similar basic approach, although the radial rate of growth dr/dt was used for the bubble velocity in the Reynolds group, showed that ... 

In the absence of experimental data, the correlation given by Forster and Zuber<86) may be used to estimate pool boiling coefficients, although the following reduced pressure correlation given by M()STlNSKl(9ri) is much simpler to use and gives reliable results for h (in W/m2 K) ...

The growth of Bacillus subtilis may take place under a variety of conditions (a) aerobic conditions, (b) using nitrate as electron acceptor, and (c) fermentative conditions with glucose provided pyruvate is available as an electron acceptor since the organism lacks pyruvate formate hydrogen lyase (Nakano and Zuber 1998).

It is important to check that the design, and operating, heat flux is well below the critical flux. Several correlations are available for predicting the critical flux. That given by Zuber et al. (1961) has been found to give satisfactory predictions for use in reboiler and vaporiser design. In SI units, Zuber s equation can be written as ... 

The maximum heat flux for stable nucleate boiling will, however, be less for a tube bundle than for a single tube. Palen and Small (1964) suggest modifying the Zuber equation for single tubes (equation 12.64) with a tube density factor. This approach was supported by Palen et al. (1972). 

Check maximum allowable heat flux. Use modified Zuber equation.
