摘要

The polymer melting mechanism in a novel extruder with extra axial vibration was studied. A self-amended non-isothermal Maxwell constitutive equation was used in simulating the special flow patterns of melt in the melt film between the driving wall and the solid/melt interface with various vibration force fields. The simulation results indicate that within a certain vibration strength range, the vibration force field can optimize the distribution of the shear rate in the flow field, thus accelerates the melting process.
