There has been significant commercial interest in the use of o scillating foil energy converters (OFECs) to extract renewa ble energy from tidal streams. The majority of research into OFE Cs has focused on a foil undergoing a prescribed pitch and heave and does not take into account the complex fluid-structure in teraction found in commercially developed elastically suppor ted OFECs. To address this need, an experimental investigation was conducted of a model OFEC undergoing a prescribed pitch…

A biomimetic semi-activated oscillating-foil device with multiple foils in a parallel configuration is studied for the extraction of marine renewable energy. For the present investigation, an

A Model for Performance Estimation of Flapping Foil Operating as Biomimetic Stream Energy Device

The performance of the above flapping-foil, biomimetic flow energy harvester is investigated by application of a semi-3D model based on unsteady hydrofoil theory and the results are verified by comparison to experimental data and a 3D boundary element method based on vortex rings.

Numerical Study of an Oscillating-Wing Wingmill for Ocean Current Energy Harvesting: Fluid-Solid-Body Interaction with Feedback Control

The performance and flow around an oscillating foil device for current energy extraction (a wingmill) was studied through numerical simulations, which could allow for the system identification, control synthesis, and optimization of energy harvesting devices in future studies.
