Dispersion coefficients summary

Rough estimates for axial dispersion coefficients can be made using random walk techniques, and these will be discussed in Section II,E. Also, a theory can be developed for predicting axial dispersion coefficients from radial dispersion coefficients which is the source of the dotted line of Figure 8. This will be discussed in Section II,D. Bischoff (B13), Fro-ment (F9), and Hofmann (Hll) have presented summaries of packed-bed data. 

Its value D is determined as summary value of effective diffusion coefficient and mechanical dispersion coefficient ...
