摘要

聚合物流变学多学科交叉特点致使其教学和科研均落后于高分子科学其它分支的发展。针对流变学教学过程中的诸多抽象概念和理论

将计算流体力学(CFD)数值模拟的方法引入到教学中

本文采用Weissenberg效应、二次流、挤出胀大和螺杆共混几个实例说明黏弹与牛顿流体本质差异

并引导学生如何将流变学的原理和方法应用到工程设计实践中

同时借用其工程设计应用功能来讲解经典流变学基本原理和理论。CFD数值模拟方法的引入使课程结构得到优化

教学方法也更为直观生动

提高学生学习的积极性。

Abstract

The teaching and research of polymer rheology fall behind those of other fields of polymer science because of the interdisciplinary characterization of polymer rheology. The numerical simulation based on computational fluid dynamics (CFD) was introduced to the course in order to improve the comprehension of students for basic concepts of polymer rheology and motivate students’ interest in learning. Several corresponding examples such as Weissenberg effect

secondary flow

die swell and screw mixing are provided to investigate the essential difference between the viscoelastic fluid and Newtonian fluild

and guide the students how to use polymer rheology in the engineering designs. Meanwhile

the applied function of engineering designs for polymer rheology is used to explain the fundamental principles of polymer rheology. Therefore

the method is favorable to optimizing curriculum structures and improving the quality of teaching.
