Computational fluid dynamics modeling of corrugated static mixers for turbulent applications / Mirella Coroneo in Industrial & engineering chemistry research, Vol. 51 N° 49 (Décembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 49 (Décembre 2012) . - pp. 15986-15996 Titre : Computational fluid dynamics modeling of corrugated static mixers for turbulent applications Type de document : texte imprimé Auteurs : Mirella Coroneo, Auteur ; Giuseppina Montante, Auteur ; Alessandro Paglianti, Auteur Année de publication : 2013 Article en page(s) : pp. 15986-15996 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Static  mixer  Modeling  Computational  fluid  dynamics Résumé : This work is aimed at investigating the capability of a fully predictive computational fluid dynamics (CFD) approach to catch the main features of the liquid flow in pipelines equipped with corrugated static mixer inserts. The simulations are based on the numerical solution of the Reynolds averaged Navier—Stokes equations on the three-dimensional domain closely representing the static mixer geometry. As a benchmark, literature experiments on a laboratory scale SMV mixer were considered and the simulation results obtained at different locations were compared with relevant velocity and tracer concentration data. The effect of the turbulence modeling, the near-wall treatment, and the numerical approximations on the accuracy of the results is discussed. The results analysis demonstrated that the selected CFD model can be reliably adopted to evaluate the velocity field and the mixing performances of turbulent flows in static mixers for design and optimization purposes. On the other hand, the application of the same model to an industrial scale corrugated plate mixer highlighted the effects of the distributor geometry and of the distance between consecutive elements on the mixing of two miscible liquids.

Numerical and experimental fluid - dynamic analysis to improve the mass transfer performances of Pd − Ag membrane modules for hydrogen purification / Mirella Coroneo in Industrial & engineering chemistry research, Vol. 49 N° 19 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 19 (Octobre 2010) . - pp. 9300-9309 Titre : Numerical and experimental fluid - dynamic analysis to improve the mass transfer performances of Pd − Ag membrane modules for hydrogen purification Type de document : texte imprimé Auteurs : Mirella Coroneo, Auteur ; Giuseppina Montante, Auteur ; Alessandro Paglianti, Auteur Année de publication : 2010 Article en page(s) : pp. 9300-9309 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Purification  Mass  transfer  Hydrodynamics Résumé : This work is aimed at investigating the impact of the fluid flow features on the behavior of gas separation membrane modules. The investigation is carried out by particle image velocimetry (PIV) experiments and computational fluid dynamics (CFD) simulations. The experimental velocity data collected in a laboratory scale membrane module confirm the reliability of the gas velocity field calculated numerically solving the Navier-Stokes equations by a general-purpose finite volume CFD code, and the effect of the observed nonideal flow distribution on the module separation performances is discussed. Afterward, the case of a pilot scale module equipped with three Pd-Ag membranes, which are well-suited for the separation of H2 from methane steam reforming gas mixtures, is considered. The appropriateness of the selected CFD method for the design and the geometric optimization of membrane modules of pilot size is demonstrated.
