High mixing efficiency that is of great importance in various industrial processes is a significant feature of spinning disk reactors. This work was focused on the characterization of mixing in a new reactor called Double Spinning Disk Reactor (DSDR) by adopting a competitive parallel reaction system known as iodide–iodate test reaction. The proposed DSDR consists of two coaxial rotating disks that the feeds are introduced into the gap between them. The mixing improves with an increase in the rotational speed of the disk, the radial distance of the feed introduced through the lower disk, and its number of feed points, while an increase in each of the feed flow rate and the distance between the disks reduces the mixing quality. Using Interaction by Exchange with the Mean model the mixing time was estimated and its value was dropped down to 4 ms under the most efficient mixing conditions.

在各种工业过程中非常重要的高混合效率是旋转盘式反应器的重要特征。这项工作的重点是通过采用称为碘化物-碘酸盐测试反应的竞争性并行反应系统，在称为双旋转盘式反应器（DSDR）的新反应器中进行混合的表征。拟议的DSDR由两个同轴旋转盘组成，将进料引入到它们之间的间隙中。随着圆盘转速，通过下部圆盘引入的进料的径向距离及其进料点数量的增加，混合得到改善，而进料流量和圆盘之间的距离的增加均减小混合质量。
