A spinning disk reactor (SDR) is one of the important process intensification devices. Previous studies primarily focused on the dependence of the liquid flow in a SDR on the operational conditions and liquid properties. However, the effect of hydrophobicity of the disk’s surface on the liquid flow in a SDR is rarely reported. In this work, the disk with a hydrophobic surface was prepared, and the effects of surface hydrophobicity, liquid flow rate, rotational speed, and liquid viscosity on the liquid flow patterns as well as the average diameter of a liquid droplet (d_avg) were investigated by a visualization method. An empirical correlation of d_avg was suggested, and the deviations were within ±15% when the calculated values of d_avg were compared with the experimental data.

具有疏水表面的旋转盘式反应器中液体流动的可视化研究

旋转盘式反应器（SDR）是重要的工艺强化设备之一。先前的研究主要集中在SDR中的液体流量对操作条件和液体特性的依赖性上。但是，很少报道磁盘表面疏水性对SDR中液体流动的影响。在这项工作中，制备了具有疏水表面的圆盘，并且表面疏水性，液体流速，旋转速度和液体粘度对液体流动方式以及液滴的平均直径（d _avg）的影响是通过可视化方法进行调查。提出了d _avg的经验相关性，当d _avg的计算值出现偏差时，偏差在±15％以内与实验数据进行了比较。
