CFD Simulation of Perforation - Pipe Liquid Distributor in Structured Packing Columns

Liquid distributors are widely used in packed columns. In this work, first, the Moore-Rukovena (1987) and Bilingham-Lockett (1997) theories which are explained the quality of liquid distribution is mentioned, then, the conditions for a good liquid distributor and types of liquid distributor are presented. Finally the distribution of liquid in perforated-pipe liquid distributor is analyzed by CFD simulation. The results of simulation show the high liquid velocity in the right side of distributor, good liquid distribution in center area of perforated-pipe liquid distributor and maldistribution in far from center area.
