Flow Visualization andThree-Dimensional CFD Simulation of the Annular Region of an Annular Centrifugal Extractor / Sandesh S. Deshmukh in Industrial & engineering chemistry research, Vol. 47 N°10 (Mai 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°10 (Mai 2008) . - p. 3677-3686 Titre : Flow Visualization andThree-Dimensional CFD Simulation of the Annular Region of an Annular Centrifugal Extractor Type de document : texte imprimé Auteurs : Sandesh S. Deshmukh, Auteur ; Jyeshtharaj B. Joshi, Auteur Année de publication : 2008 Article en page(s) : p. 3677-3686 Langues : Anglais (eng) Mots-clés : Computational  fluid  dynamics  (CFD)  ;  Annular  centrifugal  extractor  (ACE) Résumé : The single phase flow patterns in the annular region of an annular centrifugal extractor (ACE) have been studied both experimentally and computationally. Experiments were conducted using particle image velocimetry (PIV) and laser Doppler velocimetry (LDV) to understand the flow patterns and velocity profiles in both the presence and the absence of the net flow through the annulus. The data obtained in these experiments have been used for the validation of the computational fluid dynamics (CFD) simulations. Further, complete energy balance has been established. The CFD simulations were performed over a wide range of operating conditions. In contrast with the Taylor annular region (having no end effects), the ACE was found to exhibit markedly different cell patterns. The number of cells was found to be strongly dependent on the Taylor number. The effect of the internals such as radial baffles in the annulus, as well as vanes on the bottom plate, on the flow patterns has been investigated. From the simulations it was revealed that the flow patterns in ACE were also dependent on the start-up procedure of the equipment.

Residence time distribution and flow patterns in the single-phase annular region of annular centrifugal extractor / Sandesh S. Deshmukh 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. 37-46 Titre : Residence time distribution and flow patterns in the single-phase annular region of annular centrifugal extractor Type de document : texte imprimé Auteurs : Sandesh S. Deshmukh, Editeur scientifique ; Mayur J. Sathe, Editeur scientifique ; Jyeshtharaj B. Joshi, Editeur scientifique Année de publication : 2009 Article en page(s) : p. 37-46 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Two  concentric  cylinders  Residence  time  distribution  Annular  centrifugal  extractor Résumé : Flow between two concentric cylinders with high-speed rotation of the inner cylinder, also termed as turbulent Taylor−Couette flow, is an integral part of annular centrifugal extractor (ACE). The vortex motion in the annular region causes intense mixing, of the two liquids, and their separation occurs in the inner cylinder under centrifugal action. In the present work, a systematic study of residence time distribution (RTD) in the annular region of ACE has been carried out experimentally as well as using computational fluid dynamics (CFD). The effects of rotational speed (10 ≤ ω ≤ 40, r/s), aspect ratio of annulus (11 ≤ Γ ≤ 48), width of annular gap (1.5 ≤ d ≤ 6.5, mm), and the flow ratio of the immiscible fluids (0.73 ≤ FR ≤ 2.4) have been systematically investigated. Effect of flow ratio, annular gap, and rotational speed has been investigated on the RTD. It was found that the flow in ACE is near to back-mixed behavior because of the presence of counterrotating vortices. The number of vortices depends on the rotational speed and the geometrical parameters of ACE. An attempt has been made to reduce back-mixing by providing radial baffles in the annulus. Good agreement was observed between the experimental measurements and CFD predictions of RTD.
