对螺杆挤出机固体输送、熔融和熔体流动三个区域的聚合物流动进行了同时有限元模拟，而不是单独分析。螺杆挤出机螺旋流道中的流动可近似为两个平行平板之间的流动。分析了各种工艺参数、设计参数和材料性能对熔融聚合物所需的流量和通道长度的影响。
Instead of separate analyses of the polymeric flow in the solid conveying, melting and melt flow regions of a screw extruder, a simultaneous finite element simultation of the flow in the three zones of an extruder is presented. The flow in the helical channel of a screw extruder is approximated by a flow between two parallel plates. The effect of various processing variables, design parameters and material properties on the flow rate and the length of channel required for melting the polymer is analyzed.
