摘要
应用罚函数有限元和边界元法,对啮合同向双螺杆排气段内非牛顿等温粘性流场进行了数值模拟,并由此计算了螺槽内熔体充满系数与其它有关工艺参数和螺杆几何参数之间的关系。
By means of penalty finite element and boundary
element methods, the numeric simulation was conducted on the isothermal nonnewtonian flow in
the venting zone of a closely intermeshing corotating extruder. Thereafter, the dependence of the
filling degree on the relative processing parameters and the screw configuration was worked out
and analysed.
