Simulation on the Mixing Efficiency of Kenics Mixer

The strain rate in rotary Kenics mixer was calculated during mixing using a finite element(package),Fluent.The relationship between mixing efficiency and rotating speed was got.The mixing efficiency increased with the rotating speed of the mixer elements.At the same time,the influence of the gap between the elements and mixer wall on the mixing efficiency was simulated and analyzed.With the gap decreasing,the gap was beneficial to the mixing efficiency of static Kenics mixer,but this influence was very weak to rotary Kenics mixer.
