  1. Karman vortex street effect

    卡曼渦道效應
  2. Karman vortex street

    卡門渦街
  3. By using the method of construct boundary condition at the entrance, it did a research on the formation principle of karman vortex and believed that there was no direct relationship between the formation and the object itself. the existence of the object just provided a basic current in the space to generate a absolutely unstable district and so the explanation of absolutely unstable model near wake flow is more suitable

    通過採用構造入口邊界條件的方法，對k rm n渦街的形成機理進行研究，認為渦街的生成與物體本身無直接關系，物體的存在只是在空間內提供了可以產生絕對不穩定區域的基本流，因而近尾跡絕對不穩定模式的解釋較為合適。
  4. 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

    文中給出了雷諾數等於10時的升力系數計算結果並與理論值進行了對比，在一定范圍內與理論值有可比性。
  5. The relationship between the non - dimensional drag coefficient of sma plate face and time is presented, and the pressure distribution on and around the sma plate surface as well as the karman vortex configuration in the wake at a certain time are given

    給出了形狀記憶合金薄板表面的流體無量綱阻力系數隨時間的變化關系，同時給出了某一時刻薄板表面及其周邊的壓力分佈和薄板尾跡中的卡門渦街形態。
