摘要
利用有限元法对聚乙烯熔体在新型一字型排列三螺杆反应器中的流动情况进行了有限元分析,计算了三螺杆反应器整个流道的速度分布、压力分布和粘度分布。利用速度场和压力场编制了后处理程序,计算了新型三螺杆反应器的挤出特性参数。计算结果表明,三螺杆反应器在物料输运、分散性混合以及分布性混合能力等方面都具有较好的应用特性。
The flow of polyethylene melt in new style tri-screw extruder is analyzed by FEM. The pressure, velocity and viscosity fields are calculated. Based on above results, the post-processing program is employed to calculate the extrusion characteristics of tri-screw extruder. The results show that tri-screw has excellent applied abilities in the aspect of material transportation, distributive and dispersive mixing ability.
