Optimization of angular velocity of drum mixers

Analysis and Optimization of Kenics Static Mixers

The mapping approach is applied to study the distributive mixing in the, widely industrially used, Kenics static mixer. The flexibility of the mapping method makes it possible to study and compare thousands of different mixer layouts and perform optimization with respect to macroscopic homogenization efficiency and interface generation. In the paper two different designs of the mixer are invest...

Numerical study on the jet dynamic through centrifuge spinning: influence of angular velocity

Integrating rotation from angular velocity

The integration of the rotation from a given angular velocity is often required in practice. The present paper explores how the choice of the parametrization of rotation, when employed in conjuction with different numerical time-integration schemes, effects the accuracy and the computational efficiency. Three rotation parametrizations – the rotational vector, the Argyris tangential vector and t...

Comparison of the Maximum Angular Velocity of Lower Limb Joints in Different Methods of Zenkotsu Dachi in Karate

Objective: The proper implementation of Dachi in karate as a basic technique has a direct impact on the implementation of other techniques. Therefore, the aim of the present study was to compare the maximal angular velocity of hip, knee and ankle joints in differen  Zenkotsu dachi techniques in karate. Methods: 12 male karate athletes (Height 175 ± 5, mass 75 ± 5, Age 25 ± 5, Background 8 ± 2)...
