Mixing of newtonian and non-newtonian fluids in a cylindrical mixer equipped with a side-entry impeller / Jaime Sossa-Echeverria in Industrial & engineering chemistry research, Vol. 51 N° 46 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 46 (Novembre 2012) . - pp. 15258-15267 Titre : Mixing of newtonian and non-newtonian fluids in a cylindrical mixer equipped with a side-entry impeller Type de document : texte imprimé Auteurs : Jaime Sossa-Echeverria, Auteur ; Fariborz Taghipour, Auteur Année de publication : 2013 Article en page(s) : pp. 15258-15267 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Agitator  Mixer  Non  Newtonian  fluid  Mixing Résumé : The effects of rheological properties on the mixing flow generated in a cylindrical tank equipped with a side-entry impeller were investigated using particle image velocimetry (PIV). Velocity vector maps were obtained from the laminar and transitional flow regimes of viscous Newtonian and non-Newtonian shear-thinning fluids with yield stress. Radical changes in the discharge angle were detected under the evaluated conditions. It was observed that radial discharge and a strong tangential flow arise when the viscous forces dominate the flow. Moreover, the impeller discharge is affected when the interaction between the flow and one of the walls of the vessel is significant; thus, the flow features are defined by the Reynolds number and the restrictions imposed by the walls of the tank.
