Configurations and methods for ribbed downcomer wall

摘要

An inclined fluid receiving surface (230) is positioned a short distance away from a pipe distributor (210) having a plurality of openings (212) and receives from the openings a liquid-containing fluid (220) with a horizontal momentum (222) in the direction of the pipe flow. The fluid receiving surface (230) further includes a flow-impeding portion (232) that reduces the horizontal momentum (222) of the fluid (220) on the fluid receiving surface (230), thereby significantly improving distribution of the fluid (220).
