Fluid–Structure Interaction Simulation of Vortex-Induced Vibration of a Flexible Hydrofoil [PDF]
Journal of Vibration and Acoustics, Transactions of the ASME, 2017 Fluid–structure interaction (FSI) is investigated in this study for vortex-induced vibration (VIV) of a flexible, backward skewed hydrofoil. An in-house finite element structural solver finite element analysis nonlinear (FEANL) is tightly coupled with the open-source computational fluid dynamics (CFD) library openfoam to simulate the interaction of a ...

Cavity induced vibration of flexible hydrofoils [PDF]
Journal of Fluids and Structures, 2014 The objective of this work is to investigate the influence of cavity-induced vibrations on the dynamic response and stability of a NACA66 hydrofoil at 8° angle of attack at Re=750 000 via combined experimental measurements and numerical simulations. The rectangular, cantilevered hydrofoil is assumed to be rigid in the chordwise direction, while the ...

Control of a flexible, surface-piercing hydrofoil for high-speed, small-scale applications [PDF]
2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017 In recent years, hydrofoils have become ubiquitous and critical components of high-performance surface vehicles. Twenty-meter-long hydrofoil sailing craft are capable of reaching speeds in excess of 45 knots. Hydrofoil dinghies routinely travel faster than the wind and reach speeds up to 30 knots.
