Popis: Heat transmission to agitated non-Newtonian liquids in a jacketed vessel has been studied. Heat transfer tests were conducted under unsteady-state conditions with pseudo-plastic solutions (behavior index range: 0.343 to 0.633). For a generalized Reynolds number ranging from 100 to 5000, two correlations were found: The use of a generalized Sieder and Tate number resulted in an equation combining both heating and cooling data with a somewhat higher mean deviation (19.3%): Nous avons etudie le transfert de chaleur en regime d'etablissement a des fluides non-Newtoniens dans un reservoir a chemise chauffante avec agitation. Des solutions pseudoplastiques dont l'indice de comportement viscosimetrique varie de 0.343 a 0.633 ont ete utilisees. Deux relations, valides pour des nombres de Reynolds generalises variant de 100 a 5000, ont ete determinees: Nous avons combine ces deux equations en utilisant le nombre de Sieder & Tate generalise mais la deviation moyenne est plus elevee, soit 19.3%
