Modeling the Temperature Development of Wall-slipping Polymers in Single-screw Channels

  • M. Kurte-Jardin , H. Potente , K. Sigge and M. Bornemann

Abstract

Wall-slipping materials show lower melt temperature increase than wall-adhering materials on account of the reduced dissipated power component in the system, as is set out in Potente and Kurte-Jardin (2005) and Potente et al. (2005a). Up until now, however, there have not been any models for describing the development of the melt temperature in a single-screw channel when wall-slipping polymers are being processed. For this reason, a methodology of predicting the melt temperature is described. The new model is based on an existing analytical procedure that has been extended by numerical flow simulation results of isothermal 2,5D FE calculations. A comparison of the predicted mean melt temperatures with non-isothermal 3D FE flow simulation results leads to good agreement, what justifies further investigations.
