摘　　要：利用计算流体力学方法,以抚顺石化公司化塑厂在役双螺杆反应器熔体输送段为研究对象,对聚乙烯熔体在同向啮合型双螺杆反应器中的流动进行了三维等温非牛顿流场分析,求出了速度场、压力场、粘度场的基本规律以及螺杆特性曲线。结果表明,聚乙烯熔体在同向啮合型双螺杆反应器中得到了充分的混合。Twin screw reactor is a new-style reactor which is of high efficiency and hardly contaminative. Three-dimensional flow field analysis of flight element in a co-rotating twin screw reactor was calculated by CFD method and the rule of velocity field,pressure field, viscosity field, and characteristic curve were obtained. The numerical results showed that LDPE melt was fully blended in the co-rotating intermeshing twin screw extruder.
