摘　　要：利用ANSYS有限元分析软件对啮合同向双螺杆挤出机由捏合盘和螺纹元件组合而成的流道进行了三维等温非牛顿模拟分析 ,得到了组合流道的速度场和压力场。并对螺纹元件流道、捏合块流道及组合流道的流量、回流量、拉伸速率、剪切速率及剪切应力进行了比较。Three-dimensional flow simulations of combined element, including flight elements and kneading blocks in an intermeshing co-rotating twin screw extruder is performed by ANSYS.Pressure and velocity profiles are obtained.Effects of kneading blocks,screw elements,and combined runners in mixing are analyzed by comparing flight elements,kneading blocks and combined elements.
