Perforations assist in redistributing the liquid film on the complex surface of corrugated andperforated metallic sheets of structured packing, used in distillation columns. Depending on the inertial, gravitational, viscous, and capillary contributions, falling liquid film undergoes different modes of transition (rim, jet, drops, or liquid curtain) in the perforation, promoting the exchange of liquid between two faces.Our objective is to examine the hydrodynamics of these modes. We constructed an experimental setup to study the modes of transition and liquid film repartition. A simplified geometry, yet pertinent, is considered to characterize the role of perforations in corrugated and perforated packing. The basic configuration consists of ...
