摘　　要：利用大型有限元软件包ANSYS,对非牛顿流体在双螺杆反应器中的流动进行了三维流场分析,采用幂律模型求出了流道的速度场、压力场和粘度场,并对这些参数在3个跟踪点随螺杆转速和进、出口压差的变化进行了记录。研究结果对双螺杆反应器的优化设计和聚合物挤出加工有一定的理论指导意义。Three-dimensional flow modeling of non-newtonian fluid in the twin screw reactor has been carried out by using the finite element package ANSYS. The distributions of the velocity, pressure and viscosity in the flow channel are simulated by power law. These parameters at three trail points are also calculated at different rotate speeds and under different pressure difference. The research results put forward the theoretical instruction of the design of twin screw reactor and the process of polymer extrusion.
