| Abstract: | Several aspects of the downcomer's optimization is reviewed-modifying the downcomer apron shape for improving the fluid form; choosing the reasonable downcomer clearance; changing the inlet weir and intensifying the entry area. Some of optimized downcomers and trays with special downcomers are presented. Such as sloped doencomer, crescent downcomer, FRI tray and MD tray etc. In addition, the study of downcomer performance is also summarized. |
