聚合物熔体狭缝流动的有限元计算

Finite Element Method for Calculating Polymer Melt Flow in Thin Gaps

提出了一种新方法——有限块法．它可把三变元问题降低到二变元，因而大大节省了计算机内存，缩短了计算时间．本文用此法计算了狭缝流道中熔体流动。

This paper gives a new method the finite block method, which may lower 3 dimensional problems to 2 dimensional ones, so a great deal of computer internal memory and computation time are saved. The 3 dimensional flow in thin gaps is calculated with this method, and the results are satisfactory.
