摘要

Abstract

In this paper

the numerical predictions of 3D hydrodynamics and power consumption in a vessel stirred bymultiple eccentrically located impellers are presented. The vessel is a flat-bottomed cylindrical one equipped with six-curved bladed impellers. Aqueous solutions of xanthan gum are used

which have a shear thinning behavior with yield stress. The influence of several parameters on themixing efficiency has been investigated

namely:the stirring rate

fluid rheology

impeller number and impeller clearance fromthe tank bottom. Our predicted results are compared with other experimental data and a satisfactory agreement is found.
