Titre : The mapping method for mixing optimization : Part I : The multiflux static mixer Type de document : texte imprimé Auteurs : P. G. M. Kruijt, Auteur ; O. S. Galaktionov, Auteur ; G. W. M. Peters, Auteur ; Han E. H. Meijer, Auteur Année de publication : 2001 Article en page(s) : p. 151-160 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : The development of the mapping method [1, 2] and its application to viscous flow in a (multiflux) static mixer [3] is discussed. The mapping method describes the repeated transport of fluid from one domain to another and computes the concentration distribution, yielding a unique mixing measure, like e.g. the intensity and/or scale of segregation [4, 5], the residence time distribution and structure parameters like e. g. the area tensor [6].
In the multiflux static mixer, the domain is a (two dimensional) cross-section of the flow channels at the beginning and end of a single element. Since static mixers are build of a sequence of similar elements, we only need to determine one mapping matrix (a computationally expensive operation). To simulate the complete mixer, the mapping matrix is repeatedly applied (a computationally cheap operation). Three different geometries are analyzed. It is shown that an approach like the mapping method is a prerequisite in order to obtain meaningful results after a number of mixer elements. Moreover, it enables optimization of industrial mixers.Note de contenu : - Multiflux static mixer

Titre : The mapping method for mixing optimization : Part II : Transport in a cororating twin screw extruder Type de document : texte imprimé Auteurs : P. G. M. Kruijt, Auteur ; O. S. Galaktionov, Auteur ; G. W. M. Peters, Auteur ; Han E. H. Meijer, Auteur Année de publication : 2001 Article en page(s) : p. 161-171 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : The application of the mapping method [1, 2] on fully three dimensional flows with dynamic boundaries is presented. The computational domain is a (three dimensional) section of a particular type of screw element in a closely intermeshing corotating twin screw extruder. Screw elements include transport, different kneading, and counterconveying zones, for each of which a mapping matrix has to be constructed.
In the future, different screw assemblies could be studied by combining distinct mapping matrices, much like an actual screw is assembled from distinct modules. In this paper, the principle and applicability of the mapping method is demonstrated by the analysis of a fully filled transporting section of the corotating twin screw extruder. Concentration and residence time distribution can be computed straightforwardly and the volume average intensity of segregation is chosen as a characteristic mixing measure to quantitatively describe distributive mixing.DOI : 10.3139/217.1637 En ligne : https://drive.google.com/file/d/1taPB5F_u0xMs21Yvr-E5TVugnJX8obkq/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=15896
