摘要
本文建立了同向旋转双螺杆挤塑机中熔体输送流场的物理模型和数学模型,然后用罚函数有限元法及边界元法对这一非牛顿不等温、且含三个方向速度的流场进行了求解.
In this article, a model is set up both physically and numerically for the meltconveying flow field in a corotating twin-screw extruder. Then the flow field is calculated by means of the penalty finite element method and the boundary element method, thus paving the way for the study of the melt- conveying mechanism.
