Popis: An extensive study is presented on the polymer melt flow with slip effects in a single screw extrusion process. Fully three-dimensional non-Newtonian FEM computations are performed to design the screw pumping characteristics and the die characteristics which may be implemented into the composite model of the process. ANSYS Polyflow software is applied to model the melt flow in the extruder. An analysis is performed for the flow of polymers with slip effects both in the screw (on the screw and barrel surfaces) and in the die. Screw pumping characteristics and die characteristics are calculated and modeled for various power law indices, and various slipping parameters. The effect of slipping on extruder operation is discussed.
