3D/2D hybrid model for ribbon impellers operating in laminar regime

Abstract In the study a 3D/2D hybrid model for ribbon mixers, for a laminar range of mixing was verified. Distributions of the experimental and model values of velocity components and the experimental and model values of mixing power for this type of mixers were compared. Further on, based on the model solutions the optimum parameters of ribbon agitators due to the time of homogenization were established.
