Hochman-Effron correlation

Die Reynolds and Peclet numbers are based on the superficial liquid velocity, whereas c/p and au are expressed in cm and cm2/cm3, respectively. For gas-phase dispersions, the Hochman-Effron correlation is available (Satterfield, 1975) ... 

Trickle-bed models assume plug flow for both phases. Thus, it is interesting to evaluate the respective Peclet numbers. The correlations of Michell-Furzer for liquid (eq. (3.417)) and Hochman-Effron for gas (eq. (3.419)) are used and the results are shown in Table 5.15. The Reynolds number for the gas phase is 32.28. 

If we set Co and in the criterion of equation (i) as the inlet and outlet concentrations of sulfur, the effect of axial dispersion can be evaluated quantitatively. We will employ the correlation of Hochman and Effron [J.M. Hochman and E. Effron, Ind. Eng. Chem. Fundls., 8, 63 (1969)] for Peclet number...
