水漩涡/旋涡/涡旋/涡流--科技馆展品展项方案
展示内容
展项由展台、防护罩及水源、按钮等装置构成，通过机电互动的方式来演示漩涡的形成。互动时，按下按钮接通电源，搅动叶轮制造涡旋。
科学原理
水流旋转，液面沿桶壁爬升，与此同时筒内形成涡旋，涡心形状为中空漏斗状。科技馆展品制作生产源头工厂-上海惯量自动化有限公司提示大家通过按下按钮，体验到水流运动方向时钟是沿着圆筒的圆周的切线方向，这样才能产生涡旋。
操作说明
按下按钮，观察水的变化。

Exhibits of Science Museum：
vortex
The audience presses the switch and watch the formation and development trend of the vortex: the more inner it is, the faster the speed is, thus forming a very obvious vortex with its upper side bigger than its lower side, which has a phenomenon of very strong suction. Production source factory of exhibits in science museum--Shanghai GuanLiang(inertia) Automation Co., Ltd reminds everyone that The vortex has an important feature: on the same level, the arithmetic product of the velocity of a certain point and its radius keeps constant, that is, the more inner the vortex is, the faster the speed is and the less the pressure is, so the vortex has the action of centripetal suction.
