Effect of Blade Speed on Granular Flow and Mixing in a ...

The recirculating flows formed in front of the blade in cylindrical sections seem to disappear, bringing a reduction of mixing rate at high blade speeds. Viewed at the particle scale, a zone of large interparticle forces is present in front of the blade, and this zone moves toward the vessel walls at high speeds.

The number of impeller blades was varied from 1 to 4 blades, and the impact of the number of blades on granular flow behaviors and mixing kinetics was investigated. It was found that particle velocities in an agitated mixer were influenced by the number of the blades used in the mixing system. Higher radial and vertical velocities of particles were observed in the 1- and 2-bladed mixers, which ...
