Many fabrication processes for polymeric objects include melt extrusion, in which the molten polymer is conveyed by a ram or a screw and the melt is then forced through a shaping die in continuous processing or into a mold for the manufacture of discrete molded parts. The properties of the fabricated solid object, including morphology developed during cooling and solidification, depend in part ...

In this work, we study the application of Model Order Reduction (MOR) to flow plastics melt in an extrusion die. The process is described with a non-linear model consisting Stokes equations combination shear-thinning material model. reduction performed through Proper Orthogonal Decomposition (POD) approach subsequent projection. We perform a-posteriori error analysis for quantity interest, base...
