TEMPORAL EVOLUTION OF THE THERMAL FIELD OF A STIRRED TANK IN BINGHAM FLUID AND LAMINAR INERTIAL REGIME
摘要
Heat transfer to Bingham plastic fluids in an agitated vessel .It is a commonly used in chemical and food industry processes. However, little is known about the effects of mixing system geometry and the influence of rheological properties of the liquids on the heat transfer phenomenon. The hydrodynamic and thermal behaviours induced by anchor agitators, in a closed, unbaffled, batch stirred vessel. is predicted numerically by means of a Computational Fluid Dynamic (CFD) model. Heat transfer is applied on the jacketed wall of the stirred vessel. Solutions of the time-averaged Navier-Stokes and energy equations are developed using a control volume discretization method. Streamlines and isotherm represent the corresponding flow, field and the local and global distributions of Nusselt number are also presented.
