On the other hand, reports on polymers in elongational flow have appeared comparatively recently in the literature. Elongational flow with an inherent low vorticity is known to be more effective in extending polymer chains than simple shear flow and thus is more interesting from the point of view of basic (molecular chain dynamics at high deformation) and applied polymer science (rheology, fiber extrusion, drag reduction, flow through porous media). Undoubtly, one landmark in the field of polymer dynamics in elongational flow was the notion of critical strain-rate for chain extension, initially put forward by A. Peterlin (1966) and later refined into the "coil-stretching" transition by P. G. de Gennes and H. Hinch (1974). In the two decades which followed, significant progress in the understanding of chain conformation in "strong" flow has been accomplished through a combination of advances in instrumentation, computation techniques and theoretical studies. As a result of the multidisciplinary nature of the field, information on polymer chains in "strong" flow is acces | | 出版日期 | Book 1999 | | 關(guān)鍵詞 | Macromolecules; Makromoleküle; Polymere; Polymers; Rheologie; Siliconharzmasse; polymer; porous media; rheol | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-58252-3 | | isbn_softcover | 978-3-642-63515-1 | | isbn_ebook | 978-3-642-58252-3 | | copyright | Springer-Verlag Berlin Heidelberg 1999 |
