Gillis, Auteur Année de publication : 2009 Article en page(s) : pp. 4060–4074 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Discrete element method Computational fluid dynamics Fixed bed reactor Random packing structure Résumé : Packed bed unit operations are required for many commercial chemical processes. The ability to a priori predict void fraction and pressure drop in a packed bed would significantly improve reactor design as well as allow for optimization around catalyst performance, catalyst design, and the resulting process pressure drop. Traditionally, the packed bed reactor designs are based on a homogeneous model with averaged empirical correlations. These correlations are often inapplicable for low tube-to-particle diameter ratios (D/d En ligne : http://pubs.acs.org/doi/abs/10.1021/ie801548h [article] A coupled DEM and CFD simulation of flow field and pressure drop in fixed bed reactor with randomly packed catalyst particles [texte imprimé] / Hua Bai, Auteur ; Jörg Theuerkauf, Auteur ; Paul A.
