摘要
主要介绍了黏弹流体挤出胀大的数值模拟研究进展.给出了黏弹流体挤出胀大的数学模型,回顾了近20多年以来挤出胀大的主要数值模拟研究工作,然后对主要模拟方法的计算过程、方法特点和形成的结果进行了一定的总结.最后提出了作者对挤出胀大研究的一些看法,包括目前研究中存在的问题和相关研究的发展趋势.
The developments of investigations on extrudate swell by using numerical simulation methods are reviewed in this paper. The mathematical model of extrusion swelling is given first, and then the studies on swelling in the last twenty years are reviewed. The computational processes, the characteristics, and the results of the numerical methods are summarized. The authors propose their views on studying the extrudate swell and point out problems in the reported studies and the trend of investigation on swelling.
