Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°10 (Mai 2008) . - p. 3364–3371 Titre : Experimental and correlational studies of a vickers-zimmer style polyester finisher Type de document : texte imprimé Auteurs : W. Roy Penney, Auteur ; Anurag Singh, Auteur Année de publication : 2008 Article en page(s) : p. 3364–3371 Note générale : Bibliogr. p. 3371 Langues : Anglais (eng) Mots-clés : Vickers-Zimmer  disk  polyester  finisher;  Spoked-disk  style;  Mass-transfer  coefficients Résumé : An 8-in. (0.203 m)-diameter Vickers-Zimmer disk style polyester finisher was tested using carboxymethylcellulose and corn syrup solutions. The processor consisted of a spoked-disk style agitator, with 20, 5-spoke disks, in a horizontal cylindrical vessel. To prevent the liquid batch from rotating with the disks, stationary breaker bars, between each of five adjacent disks, and 210° baffle plates, between every fifth disk, were installed. Fractional liquid holdup, agitator power, angles of batch rise and depression at the vessel walls, fractional liquid film coverage of the spoked disk cutouts, and mass-transfer coefficients were all determined experimentally. Dimensionless correlations were developed for (1) fractional liquid disk holdup, (2) agitator power requirements, (3) angles of rise and depression at the vessel wall, (4) factional film coverage of the spoked wheel cutouts, and (5) mass-transfer coefficient.
