Wilson-Geankoplis correlation

For 0.0015 < Re < 55, the Wilson-Geankoplis correlation has been used in adsorption from liquid phase (Perry and Green, 1999 Xiu and Li, 2000 Chen and Wang, 2004). 

Recent work on the mass transfer kinetics in monolithic columns [74] has suggested that the Kataoka and the Penetration correlations give similar results. These results are better than those given by the Wilson-Geankoplis correlation.

The functional dependence of jD on Reynolds number has been the subject of study by many investigators [e.g., Thodos and his co-workers (77, 78), and Wilson and Geankoplis (79)]. A variety of equations have been proposed as convenient representations of the experimental data. Many of these correlations also employ the bed porosity (eB) as an additional correlating parameter. This porosity is the ratio of the void volume between pellets to the total bed volume. 

For the film transfer coefficient fcmrn, Wilson and Geankoplis (1966) developed the following correlations ... 

A plot of H/(2mq) versus 1/Ug is a straight line with a slope equal to Di and an ordinate equal to 3f + S )/Sq. The coefficient of external mass transfer is estimated using one of the several correlations available for it (see Chapter 5, subsection 5.2.5, correlation of Wilson and Geankoplis [62], Kataoka et al. [87], or the penetration theory [88]). Correcting for the contribution due to the external mass transfer resistance gives the last term in the plate height equation, 5, hence the intraparticle diffusion coefficient, Dg.
