Résumé : |
Attempts were made to predict the velocity field and shear rate distribution of a Newtonian type fluid in the KE element of the Buss Ko-Kneader by means of CFD method. The role of both rotating and reciprocating motion have been considered in three dimensional flow field. The computed results showed appreciable changes in the velocity counters during a period of reciprocating motion, and these changes were greater for the transverse flow compared to the down channel flow.
The predicted results also showed pronounced variations in the velocity profile of the transverse flow regarding both with direction and extent of drag and pressure flow as a result of reciprocating action, while the down channel velocity profile was found to be almost unaffected.
The extent of shear rate and hence shear rate distribution were found to be dominantly control by the down channel flow while transverse flow has a greater influence in determining the residence time distribution. |
