Experimental and numerical investigation of hydroelastic response of a flexible hydrofoil in cavitating flow

International Journal of Multiphase Flow, 2015
Abstract The objective of this paper is to investigate the hydroelastic response of a flexible NACA66 hydrofoil in cavitating flows by combined experimental and numerical studies. Experimental results are presented for rigid/flexible NACA66 hydrofoils fixed at α 0 = 8° for subcavitating ( σ  = 8.0) and cavitating flows ( σ  = 1.4).

The transient characteristics of cloud cavitating flow over a flexible hydrofoil

International Journal of Multiphase Flow, 2018
Abstract The objective of this paper is to investigate the two-phase flow structure of cloud cavitation over a flexible hydrofoil with particular emphasis on cavitating flow-induced vibration and the cavity shedding dynamics via combined experimental and numerical studies.

Numerical research on hydrodynamic characteristics of fish-like flexible oscillating hydrofoil

2018 IEEE 8th International Conference on Underwater System Technology: Theory and Applications (USYS), 2018
Hydrofoil is a common structure of underwater machinery and has good hydrodynamic performance. At present, most of the studies on oscillating hydrofoils are on rigid hydrofoils, but few on hydrodynamics of flexible oscillating hydrofoils. In this paper, the kinetic model of flexible hydrofoil is established by imitating tuna swimming.

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 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.

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.

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.
