Numerical simulations at the Weissenberg number as high as 2.9 were carried out by overlapping grid method and compared with experiment data .

文中采用 分区 覆盖 算法对 两种 模式在 We ＝2.9的高 Weissenberg数下进行了大量的数值 计算并与 有关实验数据进行了细致的比较。

In this paper numerical simulation of die swell for the integral Maxwell fluid is investigated employing the stress calculation method based on the conventional finite element used by Luo and the method of avoiding singularity used by Fan . The reasonable solution of higher Weissenberg number is obtained .

应用Luo提出的基于常规有限单元的应力计算 方法和范毓润回避奇点的方法，模拟了积分型Maxwell 黏 弹流体的挤出胀大流动，计算得到了 Weissenberg 数 达 1.0 下的合理结果。
