    U達到自相似狀態的起始點與渦街的對稱性被破壞的起始點是幾乎重合的，即在x h = 6 . 0處。
  8. Because the symmetrical mode of two free shear layers in the jet is destroyed at x / h = 6. 0, the vortex street develops in non - symmetrical ( sinuous ) modes downstream of this station

    由於兩剪切層的對稱性在下游x h = 6 . 0處即被破壞，之後渦街完全按非對稱模式發展。
  9. However, in real atmosphere, there exists vortex street made of two or three mesoscale vortices in typhoon eye - wall or outer region according to circulation of mesoscale structure observations

    但是，據近來臺風環流中尺度結構的觀測結果，實際大氣中，臺風眼墻或外區有時存在2 - 3個中尺度渦構成的渦列。
  10. 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。
  11. We carried numerical experiments to explore the vrw propagation features in the case of mesoscale vortex street. results show that vortex combination appears two times during vorticity propagated inner ward, with vortex street vorticity less than that of single vortex, which is a new finding in typhoon dynamics

    我們對此實施了數值試驗，結果指出：渦列渦量內傳過程中出現了兩次渦合併現象，渦列內傳的渦量比單個中尺度渦內傳的渦量要少。
  12. In the third chapter, the method and choosing principle of the test system component at first were brought out. the component of test device was introduced. and then, the characteristics, such as strouhal number, vortex street strength, vortex street stability and pressure drop coeffi

    縱觀全文，本文成功地將cfd技術和實驗流體力學方法應用於新型雙鈍體渦街流量計的研究，並對旋進旋渦流量計的流體振動特性和抗干擾方法進行系統研究，提出了旋進旋渦流量計抗干擾設計的新方法。
  13. 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。
  14. 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
