In this study, two different approaches for investigating micromixing in a rotating packed bed (RPB) with a Villermaux-Dushman protocol are presented and detailed information on the operation, design, and power consumption of the RPB is given. First, a novel nozzle liquid distribution design is investigated for micromixing. A structured approach for experimental investigations is introduced, and the influence of different liquid distribution parameters on the micromixing results is presented. It is shown that the outlet velocity from the nozzles and the liquid hold-up at the inner rim of the packing play a crucial role in the mixing process. Second, micromixing in RPBs with equal flow rates is investigated. A comparison with other continuous mixing devices is conducted based on flow rates, pressure drop, and the micromixing time parameter t_m. It is demonstrated that RPBs show a large potential for fast mixing at high flow rates and low pressure drop.

旋转填料床中的液体分配和混合

在这项研究中，提出了两种不同的方法来研究采用Villermaux-Dushman协议的旋转填充床（RPB）中的微混合，并提供了有关RPB的操作，设计和功耗的详细信息。首先，研究了用于微混合的新型喷嘴液体分配设计。介绍了一种结构化的实验研究方法，并介绍了不同液体分布参数对微混合结果的影响。结果表明，在混合过程中，喷嘴的出口速度和填料内部边缘处的液体滞留率起着至关重要的作用。其次，研究了RPB中具有相同流速的微混合。根据流量，压降和微混合时间参数与其他连续混合设备进行比较吨_米。事实证明，RPB在高流速和低压降下显示出快速混合的巨大潜力。
