Hydroelastic Responses of a Flexible Hydrofoil in Turbulent, Cavitating Flow

ASME 2010 7th International Symposium on Fluid-Structure Interactions, Flow-Sound Interactions, and Flow-Induced Vibration and Noise: Volume 3, Parts A and B, 2010
The objective of this work is to develop and validate a robust method to simulate the hydroelastic responses of flexible hydrofoil in turbulent, cavitating flow. A two degrees-of-freedom (2-DOF) model is used to simulate the plunging and pitching motion at the foil tip due to bending and twisting deformation of a 3-D cantilevered hydrofoil.

Computational Fluid Dynamics Study of a Flexible Flapping Hydrofoil Propulsor

Volume 2: CFD and VIV, 2016
A CFD study to understand the hydrodynamics and fluid flow around a chordwise flexible hydrofoil with combined sway and yaw motion which imitates the caudal fin flapping in thunniforms, is presented. The dependency of motion parameters of the flexible flapping hydrofoil to its propulsive performance is studied by carrying out the analyses over a ...

Flow-Induced Vibration of Flexible Hydrofoil in Cavitating Turbulent Flow

Volume 6: Polar and Arctic Sciences and Technology; CFD, FSI, and AI
Abstract The flow-induced vibration and cavitation dynamics of three-dimensional flow past a cantilever flexible hydrofoil are investigated using a large eddy simulation (LES) model, a homogeneous mixture cavitation model and the structural modes superposition method. The present work aims to explore a potential mechanism responsible for

Numerical Modeling of Surface-Piercing Flexible Hydrofoils in Waves

Journal of Ship Research, 2022
_ Hydrofoils made of metal alloys were broadly used on high-speed boats in the past. Nowadays, much lighter hydrofoils made of composite materials are finding increasingly more applications on sailing yachts and powerboats.

Numerical investigations of the transient cavitating vortical flow structures over a flexible NACA66 hydrofoil

Journal of Hydrodynamics, 2020
In this paper, the cavitating flow over a flexible NACA66 hydrofoil is studied numerically by a modified fluid-structure interaction strategy with particular emphasis on understanding the flow-induced vibration and the cavitating vortical flow structures.

Experimental studies on the motion of a flexible hydrofoil

Journal of Fluid Mechanics, 1964
A thin, flexible hydrofoil has been used as a model to simulate the swimming of a two-dimensional fish in an ideal, incompressible fluid, as treated in recent theoretical papers. The apparatus is described in some detail and typical data are compared with the predictions of theory.
