Title:A comparative study of viscous flow in slit-exit cross-section dies using network analysisAuthor(s):Thomas Köpplmayr, Michael Aigner, Jürgen MiethlingerAbstract:We present a systematic approach based on Kirchhoff’s laws for the analysis of complex networks that uses tensor algebra and numerical methods (such as fixed point iteration). Coathanger, fishtail, and T-manifolds are compared in terms of mass flow, residence time, and shear rate. In addition, we report the results of a three-dimensional simulation using the commercially available software ANSYS Polyflow, which were in good agreement with our numerical study.Journal:Journal of Plastics TechnologyPublisher:HanserPage Reference:page 53-74, 21 page(s)Publishing:1/2012Volume:2012Number:01
