Simulation-based analysis and optimization of polymer spin packs / Robert Feßler in CHEMICAL FIBERS INTERNATIONAL, Vol. 66, N° 3 (10/2016)  

[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 66, N° 3 (10/2016) . - p. 137-138 Titre : Simulation-based analysis and optimization of polymer spin packs Type de document : texte imprimé Auteurs : Robert Feßler, Auteur ; Dietmar Hietel, Auteur ; Christian Leithäuser, Auteur Année de publication : 2016 Article en page(s) : p. 137-138 Langues : Anglais (eng) Index. décimale : 677.4 Textiles artificiels Résumé : The simulation-based analysis is an effective tool to evaluate the overall performance of polymer spin packs, to identify design problems and to avoid misconstructions. Quality indicators rate the interplay of individual components and point out potential weaknesses. Once a problem has been identified the spin pack optimization tools help to revise the design. Every modification can be validated prior to construction. Note de contenu : - Spin pack analysis - Spin pack optimization - FIGURES : 1. Illustration of the polymer paths through a spin pack geometry - 2. Polymer spin packs offer a great potential for optimization ; the revised design has a shorter and extremely uniform residence time - 3. Optimized spin pack cavity with medium wall shear stress level (cavity A) ; the wall shear stress is indicated by color - 4. Optimized spin pack cavity with high wall shear stress level (cavity B) ; the wall shear stress is indicated by color - 5. Residence times for the optimized spin pack cavities A and B compared with a flat reference cavity En ligne : https://drive.google.com/file/d/1SoaZwB8jzPqax2TeygOVQqH0bromoBH7/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27287 [article]
