  4. Abstract:
  5. 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 micromixing time was estimated and its value was dropped down to 4 ms under the most efficient mixing conditions. © 2020 Elsevier B.V
