The fluid dynamics of flapping foils are reviewed in this article. A very wide range of
researches are conducted for the two-dimensional flapping foil which has a relatively simple …

This article presents an overview of the state of the art investigations on the recently
developed oscillating foil energy converters. A summary of available knowledge and up-to …

Power may be extracted from a flowing fluid in a variety of ways. Turbines using one or more
oscillating foils are under increasingly active investigation, as an alternative to rotary wind …

This paper reviews key issues in the physical and numerical modelling of marine renewable
energy systems, including wave energy devices, current turbines, and offshore wind …

Experimental gradient-based optimization is used to maximize the propulsive efficiency of a
heaving and pitching flexible panel. Optimum and near-optimum conditions are studied via …

Flapping wing structures have drawn increasing attention for harvesting energy from flowing
fluids. This work proposes the application of an adaptive Gurney flap to the trailing end of a …

The energy harvesting performance and resulting flow structures of a hydrofoil oscillating in
pitch and heave are studied experimentally in a water flume. The shape of a hydrofoil cross …

In the field of renewable energy, high-altitude wind energy emerges as a promising source,
particularly at altitudes (> 300 m) where conventional wind turbines cannot reach. Currently …

The ability to accurately predict the forces on an aerofoil in real-time when large flow
variations occur is important for a wide range of applications such as, for example, for …

A new type of Gurney flap is applied for energy extraction enhancement of a flapping airfoil.
Two-dimensional Navier-Stokes simulations at Re= 10 4 are conducted to study the effect of …
