Vortex shedding from a composite hydrofoil: Experimental evidence of a novel "partial lock-in"
Mohamed Farhat, Thomas Antoine Nicolas Berger, Qin Wu, Yunqing Liu
Lock-in is of great importance in many engineering applications due to its practical implications for structural safety. The influence of composite bend-twist coupling on the wake dynamics and vortex-induced vibration around a carbon fiber composite hydrof ...
Melville2023Performance potential of gas foil thrust bearings enhanced with spiral grooves
Jürg Alexander Schiffmann, Eliott Philippe Guenat
The upscaling of turbomachinery using gas foil thrust bearings is limited because of their limited load capacity and the thermal issues linked with very thin film thickness. The improvement potential of spiral grooves manufactured on the top-foil of such b ...
2019Effects of chordwise flexibility on 2D flapping foils used as an energy extraction device
The effects of chordwise pressure- and inertia-driven deformations on the power extraction potential of a kinematically constrained oscillating thin plate that undergoes a heaving and pitching motion are investigated. 2D fully coupled fluid-structure inter ...
Academic Press Ltd- Elsevier Science Ltd2017Numerical and experimental study of a nearby solid boundary and partial submergence effects on hydrofoil added mass
Mohamed Farhat, Eduard Egusquiza
The influence of the boundary conditions on the added mass of a NACA0009 cantilever hydrofoil has been numerically and experimentally investigated. The study has been focused on the effects of a lateral solid wall close to the hydrofoil tip side and of a p ...
Pergamon-Elsevier Science Ltd2014How oblique trailing edge of a hydrofoil reduces the vortex-induced vibration
François Avellan, Mohamed Farhat, Philippe Ausoni, Amirreza Zobeiri
The effect of hydrofoil trailing edge shape on the wake dynamic and flow induced vibration is investigated at high Reynolds number, Re = 0.5 x 10(6)-2.9 x 10(6). Two NACA 0009 hydrofoils with blunt and oblique trailing edges are tested. The velocity field ...
Elsevier2012Effect of Hydrofoil Trailing Edge Geometry on the Wake Dynamics
In the present study, the effect of a hydrofoil trailing edge shape on the wake dynamic and its interaction with the mechanical structure is investigated. This would help better describe the physical reasons for vibration reduction when using oblique and D ...
