摘要
非牛顿型流体在简单流动条件下可以表现出有趣的流变现象。文章介绍了流变学课程教学中引入流变实验短视频制作,让学生组队自行设计实验并制作视频,演示非牛顿流体与牛顿流体在一定流场和流动条件下的不同行为,并用于课堂实例分析的实践。这种将理论与实践相结合,制作系统性和科普性的视频作品的方式,可以培养学生的创造力,使其更好地理解课本上的知识并用于实践,同时有助于增强学生的团队合作意识和沟通能力,提高学生学习流变学的兴趣。
There are many non-Newtonian fluids in daily use that exhibit interesting rheological behaviors under simple flow conditions.In the teaching of rheology,these behaviors have been self-selected,filmed and analyzed by teams of students,showing particular deformation and shear responses under certain flow conditions.The video experiments are also analyzed as case examples.This from-theory-to-video way can be beneficial to the students for developing their creativity,further understanding the textbook knowledge and its application in realistic problems,building their teamwork and communication skills,as well as promoting their interest in studying the abstract subjects in rheology.
