Abstract

A tank is filled with a non-Newtonian fluid. We report on the deformation of the free surface resulting from the presence of an underlying vortex. In a tiny range of the experimental parameters, the flow spontaneously loses its initial axi-symmetry, leading to the formation of a stationary knife-bladed vortex. We report on the series of patterns observed experimentally and summarize the conditions of existence of the latter by establishing a state diagram.

非牛顿流体中的刃状涡

水箱里装满了非牛顿流体。我们报告了由于下伏涡的存在而引起的自由表面的变形。在实验参数的很小范围内，流动会自发地失去其初始轴对称，从而形成静止的刀叶涡。我们报告了实验观察到的一系列模式，并通过建立状态图总结了后者的存在条件。收稿日期:2016年7月1日，收稿日期:2016年10月24日;编辑:j·p·胡林;评审:C. Nouar, LEMTA，洛林大学，南希，法国;本文由E Freyssingeas, D Frelat, Y Dossmann, J-C Geminard撰写，采用知识共享署名许可3.0协议。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
