Disturbances in the hydrodynamic behavior of a spouted bed caused by an optical fiber probe / Dyrney A. Santos in Industrial & engineering chemistry research, Vol. 51 N° 9 (Mars 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 9 (Mars 2012) . - pp. 3801-3810 Titre : Disturbances in the hydrodynamic behavior of a spouted bed caused by an optical fiber probe : Experimental and CFD study Type de document : texte imprimé Auteurs : Dyrney A. Santos, Auteur ; Gustavo C. Alves, Auteur ; Claudio R. Duarte, Auteur Année de publication : 2012 Article en page(s) : pp. 3801-3810 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Computational  fluid  dynamics  Fiber  optic  sensors  Fluidization  Spouted  bed  Hydrodynamics Résumé : In this work the disturbances in the hydrodynamic behavior caused by the use of an optical fiber probe in a conical-cylindrical spouted bed have been analyzed based on experimental results and CFD simulations using an Eulerian-Eulerian multiphase model. The insertion of the probe inside the spouted bed caused a decrease in the fountain height and in the particle velocity for the spout region. The CFD simulations using the Representative Unit Cell model (RUC) drag model and considering the presence of the probe predicted better the experimental data of the particle velocity distribution than the other simulations performed in this work with other drag models.
