This article uses the finite element analysis method of thermal fluid solid coupling to study the pressure field,velocity field,and thermal deformation of the feeding tube of three different structures of extruder melt when high viscosity melt POE is introduced into the feeding tube.By numerical comparison,the optimal structure of the POE feed tube for high viscosity melt of the screw extruder can be determined.At the same time,the simulated values were compared and verified with the experimental values,and it was found that the error was within 5%.This structure provides ideas for the design and optimization of subsequent extruder connection structure schemes,while reducing equipment energy consumption and improving equipment production capacity.
