Observations of Oscillating Cavitation on a Flat Plate Hydrofoil

open access: yes, 2001
An experimental investigation was made to clarify the characteristics of oscillating cavitation on a flat plate hydrofoil in a water tunnel. Dynamic the behavior of oscillating cavitation is discussed from the unsteady pressure measurements at the ...

Numerical analysis of hydrofoil ventilated cavitation under wave impact [PDF]

open access: yes, 2009
Unsteady ventilated cavitation of a hydrofoil is analyzed with coupling of the perturbed steady two-dimensional incompressible flow of water out of the cavity and the compressible one-dimensional air flow within the cavity.

Design and Dynamic Analysis of Oscillating Hydrofoil with Bar Linkage

open access: yes, 2014
  本研究整合連桿機構作動原理與傳統的往復式發電機之設計概念,將連桿與對稱型機翼做一結合,嘗試設計出不需控制系統、或降低控制系統耗電量的連桿機構往復式發電機,並且對於發電機運作特性與性能,作一系列的討論。   首先,對於傳統的往復式發電機做運作原理的探究,接著探討連桿機構的作動原理與限制,並利用對稱型機翼結合四連桿之運動軌跡,計算其在流體中之受力,並且證明在單一對稱型機翼之下,四連桿式發電機無法藉由所受之流體力完成往復式擺盪。   接著設計出一四連桿加裝襟翼往復式發電機,並做進一步的空氣動力學討論 ...

Thrust Optimisation of an Oscillating Hydrofoil - By Non-Sinusoidal Sway and Yaw Motion [PDF]

open access: yes, 2017
Past research has shown that oscillating hydrofoils can enhance the propulsion efficiency significantly compared to traditional propellers. Dynamic stall plays an important role in the thrust generated by an oscillating hydrofoil, combining this with non-

On the dynamics and acoustics of cloud cavitation on an oscillating hydrofoil [PDF]

open access: yes, 1994
Observations have been made of the growth and collapse of surface and cloud cavitation on a finite aspect ratio hydrofoil oscillating in pitch. The cavitation was recorded using both still and high-speed motion picture photography, and the variations ...
