TL;DR: In this paper, the transient hydroelastic response and energy harvesting potential of flexible piezoelectric beams fluttering in incompressible, viscous flow were investigated, and critical non-dimensional parameters were identified to govern the response of the beam.

TL;DR: In this paper, the authors 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.

TL;DR: In this paper, the authors combined numerical and experimental studies of natural flow-induced vibrations of flexible hydrofoils to identify 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.

TL;DR: In this paper, the effect of turbulent and cavitating flow on the hydroelastic response and stability of a hydrofoil is numerically examined, and the results show that, in general, massive cavitation tends to reduce the mean lift, increase the mean drag, lower the mean deformations, and delay static divergence, while unsteady sheet/cloud cavitation promotes flow induced vibrations.

TL;DR: In this paper, the authors investigated the influence of solid-to-fluid added mass ratio (μb) and viscous effects on the fluid-structure interaction (FSI) response and stability of a flapping foil in incompressible and turbulent flows using a recently presented efficient and stable numerical algorithm in time-domain, which couples an unsteady Reynolds Average Navier-Stokes solver with a two degrees-of-freedom structural model.
