Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 11 (Juin 2010) . - pp. 5053–5060 Titre : CFD simulation of spouted beds using a pressure source term Type de document : texte imprimé Auteurs : Zhiguo Wang, Auteur ; H. T. Bi, Auteur ; C. J. Lim, Auteur Année de publication : 2010 Article en page(s) : pp. 5053–5060 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Granular phase solids phase. Résumé : An integrated granular phase source term was introduced into the vertical momentum balance equation of the solids phase in the annulus region to simulate different flow patterns in the conical spouted bed described in our previous work (Wang et al. Particuology 2006, 4, 194), as well as in a cylindrical spouted bed. This article shows a simple way to estimate the source term from the measured overall pressure drop over the spouted bed. The simulated results were found to agree very well with observed flow patterns and measured local velocity and voidage data, providing a new approach for predicting the flow structure in spouted beds.
