Numerical and experimental investigation of natural flow-induced vibrations of flexible hydrofoils

Physics of Fluids, 2016
The objective of this work is to present combined numerical and experimental studies of natural flow-induced vibrations of flexible hydrofoils. The focus is on identifying the dependence of the foil’s vibration frequencies and damping characteristics on the inflow velocity, angle of attack, and solid-to-fluid added mass ratio.

Modeling and control of flow-induced vibrations of a flexible hydrofoil in viscous flow

Smart Materials and Structures, 2016
In this paper, a reduced-order model (ROM) of the flow-induced vibrations of a flexible cantilevered hydrofoil is developed and used to design an active feedback controller. The ROM is developed using data from high-fidelity viscous fluid-structure interaction (FSI) simulations and includes nonlinear terms to accurately capture the effect of lock-in ...
