摘要
Abstract
A twin screw extruder design featuring tooth eccentric kneading blocks was suggested to enhance extrusion quality due to the inadequate mixing performance of conventional twin screw extruders.The corresponding geometric model was established with SolidWorks,and the three-dimensional flow field was analyzed in the finite element analysis software ANSYS/CFX.The study examined and compared the macroscopic pressure distribution,velocity patterns,streamline paths,shear strain rates,and extrusion capacity between the proposed twin screw extruder design and the conventional twin screw configuration.w.The results show that the pressure difference of the new twin-screw runner is smaller and the retention time of the material is increased.The existence of eccentric kneading block makes the velocity vector distribution uneven,the velocity flow line disorganized,the shear strain rate increased,and the dispersion mixing effect of the material improved.The results show that the new twin screw can improve the extrusion quality on the basis of guaranteeing the extrusion efficiency.关键词
