Lattice boltzmann method for simulation of solutal interfacial convection in gas – liquid system / Shuyong Chen in Industrial & engineering chemistry research, Vol. 51 N° 33 (Août 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 33 (Août 2012) . - pp. 10955-10967 Titre : Lattice boltzmann method for simulation of solutal interfacial convection in gas – liquid system Type de document : texte imprimé Auteurs : Shuyong Chen, Auteur ; Bo Fu, Auteur ; Xigang Yuan, Auteur Année de publication : 2012 Article en page(s) : pp. 10955-10967 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Convection Résumé : Two approaches based on the lattice Boltzmann method (LBM), the two-BGK (Bhatnagar, Gross, and Krook)-equation LBM and the hybrid LBM―finite-difference method (FDM), were developed for simulations of solutal interfacial convection. Implementations of the gravity/buoyancy and surface tension forces and an interfacial perturbation model, namely, the self-renewal interface model, were proposed for the simulation of interfacial convection, including Rayleigh convection and Marangoni convection, in a gas―liquid mass transfer process. The simulation approaches and model were validated by experimentally measured data via the particle image velocimetry technique for the CO2―ethanol system. The performances of the two simulation methods presented in this paper are discussed.
