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 …

There is great interest in small aircraft known as Micro Air Vehicles and mini Unmanned Air
Vehicles due to the wide range of possible applications. This article reviews recent work that …

This work investigates the aerodynamics of a NACA 0012 airfoil at the chord-based
Reynolds numbers (Re c) from 5.3× 10 3 to 2.0× 10 4. The lift and drag coefficients, CL and …

The vortex dynamics of leading-edge vortices on plunging high-aspect-ratio (AR= 10) wings
and airfoils were investigated by means of volumetric velocity measurements, numerical …

Force and particle image velocimetry measurements were conducted on a NACA 0012
aerofoil undergoing small-amplitude high-frequency plunging oscillation at low Reynolds …

The present study investigates the mechanisms of wake-induced flow dynamics in tandem
National Advisory Committee for Aeronautics 0015 flapping foils at low Reynolds number of …

We investigate the forces and unsteady flow structures associated with harmonic oscillations
of an airfoil in the streamwise (surging) and transverse (plunging) directions in two …

Wake evolution of an oscillating foil with combined heaving and pitching motion is evaluated
numerically for a range of phase offsets (pairs observed consistently for oscillating foils with …

We present an experimental investigation of the flow structure in the near wake of a
NACA0012 airfoil plunging sinusoidally at a chord Reynolds number of Re= 20 000 and for …

FLAPPING-WING aerodynamics has attracted a great deal of research interest recently from
both the aeronautical and biological communities; this interest pertains both to the …
