Computational Analysis of Rotating Mixing of Bird Carreau Model Fluid

Abstract

Bird Carreau model is employed under the presented study of two–dimensional rotating flow. Numerical solutions for a rotating container are carried out in terms of complex mixing flows for the case of contra rotating stirrers. The problem is relevant to the food industry. The mobility of the fluid is considered as driven by the outer rotating wall and movement of stirrers is considered in the contra rotating direction at various speeds. The solutions are obtained through a finite element semi–implicit Taylor– Galerkin/pressure–correction scheme. The method is based on second order multi–stage time–stepping algorithm posed in a cylindrical polar coordinate system. The predicted results are validated against previously simulated results and are observed identical with one and another.
