3D unsteady flow in oscillating compressor cascade [PDF]
An experimental and computational study has been carried out to enhance current understanding of three dimensional (3D) cascade aeroelastic mechanisms. 3D unsteady pressure data produced during executing this project is the first-of-its-kind, which can ...

Design and Dynamic Analysis of Oscillating Hydrofoil with Bar Linkage
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 ...

Fluid–structure coupling for an oscillating hydrofoil [PDF]
Abstract Fluid-structure investigations in hydraulic machines using coupled simulations are particularly time-consuming. In this study, an alternative method is presented that linearizes the hydrodynamic load of a rigid, oscillating hydrofoil. The hydrofoil, which is surrounded by incompressible, turbulent flow, is modeled with forced and free ...

Quantification of flow noise produced by an oscillating hydrofoil
Ocean Engineering, 2019Abstract After getting inspired from swimming natural species, a lot of research is being carried out in the field of unmanned underwater vehicles. During the last two decades, more emphasis on the associated hydrodynamic mechanisms, structural dynamics, control techniques and, its motion and path planning has been prominently witnessed in the ...
