vortex cylinder
解釋
渦流柱（螺槳）-
With the computing program, flow around the square cylinder is resolved at first, and the period of laminar flow is simulated successfully. during the period of vortex street ( re = 100 ), the periodically evolutionary phenomena of the flow behind the square cylinder can be seen
利用計算程序，本文首先對方柱繞流流動進行求解，成功模擬了方柱繞流層流階段的流動和渦街階段（ re = 100 ）方柱尾流的周期性變化現象。 -
Keywords : circular couette flow, taylor vortex, fluid instability, elliptical inner cylinder
關鍵詞：圓形庫頁特流、泰勒渦漩、流體不穩定、橢圓形內柱。 -
Result shows that the dip angle, the towed velocity and reduced velocity are main influence factors to the vortex - induced vibration of a circular cylinder
結果表明，約化速度、拖纜傾角、拖曳速度等是影響渦激振動的主要因素。 -
An experimental study on the vortex - induced vibrations of a circular cylinder was conducted to investigate the vibration of the towed - cable when the towed array sonar was dragged underwater
摘要為了考察圓柱型聲納陣拖纜在水下拖曳時，由於尾流中發放旋渦激起的渦激振動情況和有關規律，進行了試驗研究。 -
Under some conditions, vortices are alternately shed from each side of the cylinder, which induces the fluctuating forces acting on the cylinder. it decreases the operating time of the equipment. for the purpose of the long - term reliability and the safety designing of the industrial component and the theory of gas - liquid two - phase vortex street, gas - liquid two - phase vortex street is simulated by commercial software phoenics for the first
工業領域內存在著大量的氣液兩相繞流柱體的現象，一定工況下形成交替脫落的旋渦，誘發柱體受到脈動升力的作用，由此產生的疲勞損傷大大縮短了工業設備的使用壽命，為了促進氣液兩相渦街理論的發展和給工業設備的設計和安全運行提供充分的科學依據。 -
The resolute of numerical calculation indicates that, when re > 100, the karman vortex - street appeares, the pressure on the surface of the circle cylinder is pulsing ; when re < 1, back - flow is appeared ; when re = 10, the coefficient of lift is comparable with the theory in 0 < 9. 25
