摘　　要：旋转床气相压降是设计旋转床的重要技术指标之一。通过分析并流旋转床结构与工作原理,建立气相压降的理论模型。采用Eulerian多相流模型和k-ε模型对并流旋转床气相压降进行数值模拟,探索液体分布器结构对气相压降的影响。实验表明所建立的压降模型较好地解释了实验现象,孔型分布器有利于减小气相压降。The gas pressure drop is an important technical parameter in the design of rotating packed bed.The theoretical model of gas pressure drop was established by analyzing the structure and working principle of current rotating packed bed.An Eulerian multi-fluid flow model and k-ε model were developed to simulate gas pressure drop for current rotating packed bed.Besides,the influence of the fluid drop distributor on gas pressure drop was explored.Experimental results showed that the model of gas pressure drop was in good agreement with the experimental observation.Porous fluid distributor is helpful to reduce gas pressure drop.
