Application of the Network Simulation Method to Flat Dies with Inverted Prelands
Sprache des Titels:
We present a systematic approach based on Kirchhoff?s laws that uses tensor algebra and analytical formulae obtained from constitutive equations for the analysis of flow resistance networks. The flow of a Carreau fluid in a flat die with inverted preland is analyzed in terms of mass flow, velocity, and residence time distributions. Viscous heating is taken into account by using an analytical model which depends on the Cameron number of the flow at different positions. Further, we report the results of a three-dimensional simulation, using the commercially available ANSYS Polyflow software, which are in good agreement with our numerical study.
