摘　　要：旋转填充床反应器是一种典型过程强化装置,对化工过程中的传质与混合过程具有较好的强化作用。流体流动作为旋转填充床反应器中最为基础的性质,对研究、优化旋转填充床反应器的结构和性能至关重要。光学成像技术与数值模拟作为研究旋转填充床反应器中流体力学性质的重要手段在近年来得到了飞速发展。对近三十年来,旋转填充床反应器可视化研究进行了综述,从早期光学成像开始,在此基础上引入早期计算流体力学模拟,直至现在高速数码摄像可视化和基于真实结构的模拟。对旋转填充床的可视化观测从填料表面逐渐向填料内部发展,对其数值模拟从初步的数学模型发展到包含详细填料几何结构、详细流体特性的流动模拟。现有研究已对填料区、空腔区中的流体流动有了较为详细的描述。The rotating packed bed (RPB) reactor is a typical process strengthening device,which has an active effect on the mass transfer and mixing process.The fluid flow behavior as one of the most fundamental property in a rotating packed bed reactor is essential to the study and optimization of the RPB reactor.Optical imaging technology and numerical simulation have been developed rapidly in recent years as important means to study hydrodynamic characteristics in RPB reactors.In this work,the visualization researches of RPB reactor in recent 30 years have been reviewed.The visualization research of RPB gradually develops from the surface of the packing zone to the inside of the packing zone.Up to now,the fluid flow in the packing and cavity zones can be described,but the simulation of mass transfer and mixing processes and accurate visual experiment still need to be developed deeply.
