Non-isothermal flow of viscoelastic fluid in the extruder spinnerets
In this paper, we consider the non-isothermal flow viscoelastic fluid in the extruder spinnerets. In order to examine influence of relaxation properties of polymeric systems upon fluid flow in front of the forming nozzle, we chose the one-parametrical Fun Tuen-Tunner model. Also presented are the mathematical description of the process and simulation data obtained.
