Abstract
In this paper, 3D finite element numerical simulation was used on the flow in the XXXX melt pump with POLYFLOW. By numerical simulation analysis on the flow field in the melt pump, distribution characteristics of pressure, flow velocity vectors and shear rate in the melt pump were obtained. Finally, the effects of inflow rate on the pressure difference between the exit and the entrance of the melt pump were investigated by analyzing the pressure field of the melt pump, which could be used to guide the design of melt pump and the plastics molding process.
