摘 要:旋转填充床(RPB)反应器凭借填料对液体的切割破碎作用,可以显著强化多相流之间的质量传递,大幅度减少反应时间。但是旋转填充床内部结构和流体力学规律极为复杂,即便使用高速摄像机也很难准确描述填料内的流动和传质规律。计算流体动力学(CFD)凭借其能够有效模拟多相流动过程中的流动和传质规律的独特优势,近年来已被许多研究人员用来模拟RPB反应器中的流动和反应特性。本文综述了近些年来学者利用CFD技术模拟旋转填充床反应器的研究进展,并着重总结了多相流模型的选取、边界条件的确定以及旋转填充床的简化方法等CFD计算中的关键部分。The rotating packed bed(RPB)reactor can significantly enhance mass transfer efficiency between multiphase flows and reduce reaction time with the cutting and crushing effect of the filler on the liquid.However,the internal structure and hydrodynamics of a RPB reactor are extremely complex,making it difficult to accurately describe the flow and mass transfer behaviors within the packing even using high-speed cameras.Computational fluid dynamics(CFD)has been used by many researchers to simulate the flow and reaction characteristics in RPB reactors in recent years due to its unique advantages in effectively simulating the flow and mass transfer behaviors in multiphase flow processes.This article summarizes the research progress of scholars using CFD technology to simulate rotating packed bed reactors,and focuses on the selection of multiphase flow models,determination of boundary conditions,and packed bed calculations,which were key parts of CFD calculation.
