Fluid Mixing Processes

Webinar: Characterising Impeller Performance in Stirred Tanks and Potential Developments

Webinar: Characterising Impeller Performance in Stirred Tanks and Potential Developments
  • Date From 6th July 2022
  • Date To 6th July 2022
  • Price Free of charge, open to all.
  • Location Online: 13:00 BST. Duration 1 hour.


Impellers in stirred vessels are often described in terms such as high flow, high efficiency, high shear etc. These terms are qualitative and are not particularly helpful when carrying out agitator design calculations. This webinar will present a method that allows their flow and shear characteristics to be quantified and appropriate impellers selected based on process requirements.
