摘　　要：为探索旋转填料床压降的影响因素,采用Fluent软件对填料直径360mm、高150mm的CRPB3615型并流旋转床进行气液两相数值模拟研究,与实验比较得到较好验证。结果表明:旋转床内压降分布是紊乱的,气体存在局部回流现象;在一定条件下,并流旋转填料床压降随液量和气量的增大而增大,随转速的增大而减小;在气液比300(体积比)时,转速为1200r/min最优。To explore the influence factors of pressure drop in a rotating packed bed,through Fluent,air-fluid twophase numerical simulation of a CRPB3615 co-current rotating packed bed was studied.The experimental results show that the result of numerical simulation is satisfactory.The results indicate that the distribution of pressure drop is disorder and partial reflux exists in a rotating packed bed.The pressure drop of a co-current rotating packed increases with the increasing gas or liquid flux,but decreases with enhanceing rotational speed under given condition.The best rotational speed is 1 200 r/min when the gas-liquid flow ratio is 300.
