Hydrodynamics in a rotating packed bed. I. / Zuo-yi Yan in Industrial & engineering chemistry research, Vol.51 N° 31 (Août 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol.51 N° 31 (Août 2012) . - pp. 10472-10481 Titre : Hydrodynamics in a rotating packed bed. I. : A novel experimental method Type de document : texte imprimé Auteurs : Zuo-yi Yan, Auteur ; Lin Cheng, Auteur ; Qi Ruan, Auteur Année de publication : 2012 Article en page(s) : pp. 10472-10481 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Packed  bed  Hydrodynamics Résumé : A novel experimental method is proposed to investigate the fluid flow in rotating packed beds (RPB). Experimental results show that the novel method is simple and effective and can be used not only in the lab experimental equipment but also in the industrial grade equipment. By using this method, the hydrodynamic performances of the RPB can be easily studied, which include actual wetting and false wetting, the flow pattern of the liquid film flow, the number and width of liquid trajectories, etc., and consequently, their changing rules are obtained. The results have significant effect on the gas-liquid two phase transfer behavior and are the basis of establishing accurately hydrodynamic mathematical model for RPB.

II. : A mathematical model Type de document : texte imprimé Auteurs : Zuo-yi Yan, Auteur ; Qi Ruan, Auteur ; Lin Cheng, Auteur Année de publication : 2012 Article en page(s) : pp. 10482-10491 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Mathematical  model  Packed  bed  Hydrodynamics Résumé : A mathematical model for air―liquid two-phase flow in rotating packed beds (RPB) is established to describe the real condition of the fluid flow in the RPB. Results show that the model can better and reasonably predict the distribution of the air-liquid two-phase flow field, the pressure drop, the liquid film thickness, the proportion of the turbulent flow in the liquid film and some other complex hydrodynamic characteristics in the RPB. The results provide a theory basis for the gas-liquid two-phase heat transfer and mass transfer.
