An approach utilizing the automodel properties in describing the hydrodynamic behaviour of counter-current columns has been extended to regularly stacked beds. Two new kinds of the packing have been investigated: The so-called K-packing, developed in the German Democratic Republic and the Cellular packing, developed in Poland. The results of experiments have been presented in the form of plots of the normalized liquid hold-up, hp, versus the normalized liquid velocity, Ql, and two empirical correlations. A comparison with previous results with randomly packed counter-current trickle bed columns has also been made.
