| dc.description.abstract | 流變學是門探討複雜高分子材料液態流動行為之科學，其生活中最常見例子包含澱粉液、番茄醬及油漆等非牛頓流體物質，其流動性質相較一般牛頓流體(水、酒精)，黏度受溫度、剪切率影響甚大，其中最為著名的表觀現象即韋森堡效應(爬竿效應)。本研究透過自行設計的量測機構探討中筋及低筋麵粉分別與水配置的澱粉水溶液之比例在不同轉速下所形成爬竿高度差異，以質化探討不同剪切率在不同比例之澱粉溶液所形成爬竿高度差異，進而理解剪切稀化對溶液黏度影響。實驗結果顯示，爬竿高度隨著轉速越快而致使剪切率提升並導致剪切稀化效應趨於明顯而越高，此外，當溶液越濃稠(黏度越高時)，韋森堡效應越顯著。本專題研究成果及自行開發之教具預期提供學員更認識牛頓及非牛頓流體在流動行為之差異。 | zh_TW |
| dc.description.tableofcontents | Rheology is to explore the complex polymer material liquid flow operation for science, of which common examples in life include starch liquid, ketchup and paint and other non-Newtonian fluid substances, the fluidity of this kind of body compared to the more general Newtonian fluid(water and alcohol), viscosity by temperature, shear rate of the substance is very large, the most famous of which is the existing Weissenberg effect(Rod-climbing). In this study, the self-designed measuring mechanism explored the difference in the height of climbing rods formed by the proportions of medium gluten and low gluten flour and the starch aqueous solution of water configuration at different speeds, and the difference in climbing rod height formed by different shear rates in different proportions of starch solutions was discussed qualitatively, and then the effect of shear thinning on the viscosity of the solution was understood. Experimental results show that the height of the climbing rod increases with the faster the rotational speed, resulting in an increase in shear rate and a significant shear thinning effect, in addition, the more concentrated the solution (the higher the viscosity), the more pronounced the Weissenberg effect. The research results of this topic and the self-developed teaching aids are expected to provide students with a better understanding of the differences in the flow behavior of Newtonian and non-Newtonian fluids. | zh_TW |
