Abstract

In this paper, a three-dimensional model of the melt conveying section of a PVC Wood-Plastic single-screw extruder has been constructed and the corresponding mesh file has been established through Mesh Superposition Techniques (MST). Then the rheological experimental results and material viscosity model parameters obtained by polymath software have been finally used for numerical simulations which are based on Polyflow software package with PVC wood plastics as raw materials. With the contrastive discussions of the simulation results, the effects of screw arris cross section shapes on the flow fields in the melt conveying section of the PVC wood-plastics single-screw extruder have been analyzed.
