In this paper the authors studied the 3-dimensional flow behavior of the polymer solution in the screw barrel. Numerical simulation was performed in the COMSOL Multiphysics suite. An aqueous solution of polyacrylamide was regarded as a specific liquid. Demonstrated that, with a decrease in the gap between the outer tube and the screw insert core, the profile of the axial component of the velocity vector is aligned over the entire barrel crosssection, except for the region adjacent to the screw ribs.

螺杆嵌芯的半径如何影响聚合物溶液的流动行为

在本文中，作者研究了聚合物溶液在螺杆机筒中的 3 维流动行为。数值模拟在 COMSOL Multiphysics 套件中进行。聚丙烯酰胺的水溶液被视为特定液体。表明，随着外管和螺杆嵌芯之间间隙的减小，速度矢量的轴向分量的轮廓在整个机筒横截面上对齐，除了与螺杆肋相邻的区域。
