摘      要：1 INTRODUCTIONDowncomers,employed in tray columns,are widely used nowadays in industrialseparation *** function as channels for the liquid phase to fall fluentlyfrom one tray onto its neighbouring places for the held-up bubble to separate fromthe liquid *** is well known that liquid flow patterns and mixing characteristicsin downcomers are closely related to the initial liquid distribution on the tray,andhence to tray *** a long period of time,little attention has been paid
