水漩渦/旋渦/渦旋/渦流--科技館展品展項(xiàng)方案
展示內(nèi)容
展項(xiàng)由展臺(tái)、防護(hù)罩及水源、按鈕等裝置構(gòu)成,通過(guò)機(jī)電互動(dòng)的方式來(lái)演示漩渦的形成。互動(dòng)時(shí),按下按鈕接通電源,攪動(dòng)葉輪制造渦旋。
科學(xué)原理
水流旋轉(zhuǎn),液面沿桶壁爬升,與此同時(shí)筒內(nèi)形成渦旋,渦心形狀為中空漏斗狀。科技館展品制作生產(chǎn)源頭工廠-上海慣量自動(dòng)化有限公司提示大家通過(guò)按下按鈕,體驗(yàn)到水流運(yùn)動(dòng)方向時(shí)鐘是沿著圓筒的圓周的切線方向,這樣才能產(chǎn)生渦旋。
操作說(shuō)明
按下按鈕,觀察水的變化。

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.
