Features of fluid film falling on the corrugated surface of structured packings with perforations

Resumo

Some results of an experimental study of liquid film flow over the surface of a structured packing with a new design for heat and mass exchangers were presented. The influence of the irrigation density on the overflow of liquid from one side of a packing element to the other side was studied. The overflow of liquid from one side of a packing element to the other side was shown to occur abruptly upon attaining a certain irrigation density. A dimensionless quantity, namely, the overflow number, was proposed for estimating uniformity in the distribution of a liquid film over a structured perforated packing bed.
