为了进一步研究旋转填充床 (RPB) 中的传质机制，通过分析方法结合一系列实验室测量来研究 RPB 中液滴的动力学。基于流体动力学结果，分别提出了RPB传质系数和传质过程的数学模型。 RPB 中的传质实验也使用乙醇-水溶液进行。通过比较，模拟结果与实验结果吻合较好，表明流体动力学模型和传质模型都能更好地描述RPB的真实工况。 © 2014 美国化学工程师学会 AIChE J, 60: 2705–2723, 2014
To do further research on the mass-transfer mechanism in rotating packed bed (RPB), dynamics of droplets in a RPB are studied by an analytical approach combined with a series of laboratory measurements. Based on the results of the fluid dynamics, mathematical models of mass-transfer coefficient and mass-transfer process in RPB are proposed, respectively. Mass-transfer experiments in RPB are also carried out using ethanol–water solution. By comparison, the results of simulation agree well with that of the experiment, which demonstrate that both hydrodynamic model and mass-transfer models can better describe the real conditions of RPB. © 2014 American Institute of Chemical Engineers AIChE J, 60: 2705–2723, 2014
