A numerical study of taylor bubbles / Xiaozhen Lu in Industrial & engineering chemistry research, Vol. 48 N°1 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°1 (Janvier 2009) . - P. 242-252 Titre : A numerical study of taylor bubbles Type de document : texte imprimé Auteurs : Xiaozhen Lu, Editeur scientifique ; Andrea Prosperetti, Editeur scientifique Année de publication : 2009 Article en page(s) : P. 242-252 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Taylor  bubbles  Axisymmetric  Taylor  bubbles Résumé : Some results of a computational study of axisymmetric Taylor bubbles rising in a vertical tube filled with a quiescent, upward- or downward-flowing liquid are presented. The computational method is based on a finite-volume discretization of the Navier−Stokes equations on a staggered grid. The interface is maintained sharp and is discretized using a set of marker points linked by cubic splines. Independent theoretical results and published data are used for its validation. The simulations illustrate the effect of the Morton and Eötvös numbers on several steady-state and time-dependent processes.
