Abstract

From the functional relationship between the flooding gas and liquid velocities derived from the two-film theory based on the Bernoulli equation, two parameters which are relative to the packing property were investigated. One is the packing factor a/ε³ which consists of the packing specific area a and the bed porosity ε. Another is the structural parameter which was defined for the first time from this work. It was demonstrated by the present work that Raschig rings and spherical particles were belonging to the same type, and the structural parameter was found to be 1.4, while the Pall rings and Intalox saddles were belonging to a different one, and the structural parameter was 0.9. Since the effects of packing structure and packing factor are considered simultaneously, therefore, the flooding prediction is more indicative and more accurate.
