Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 21 (Novembre 2010) . - pp. 10715-10729 Titre : Fast reactions in bubbly flows : Film model and micromixing effects Type de document : texte imprimé Auteurs : Stefan Radl, Auteur ; Daniele Suzzi, Auteur ; Johannes G. Khinast, Auteur Année de publication : 2011 Article en page(s) : pp. 10715-10729 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Micromixing  Modeling  Bubble  flow  Fast  reaction Résumé : In our work, we focus on the Euler-Lagrange strategy to simulate bubbly flows and fast chemical reactions. We propose a film model to account for fast, multistep chemical reactions near the gas—liquid interface. A combination of such a film model with Euler—Lagrange simulations for bubbly flows has not been used before. Also, we account for micromixing effects with respect to chemical reactions in the liquid bulk by solving for the variance of the concentration field. To validate our model predictions for multiphase flow and reactive mixing, we compare our results with literature data and find excellent agreement.
