Abstract Effects of horizontal oscillations of the freestream velocity superimposed on a pitch
oscillating NACA0012 airfoil were investigated using Computational Fluid Dynamics (CFD) …

Slip velocity effects on the performance of an SD7037 wind turbine blade are processed.
The slip boundary condition is associated with applying a superhydrophobic coating on the …

Vertical axis wind turbine blades undergo dynamic stall due to the large angle of attack
variation they experience during a turbine rotation. The flow over a single blade was …

This study numerically investigates the behavior of vortices and flow structure in a dynamic
stall phenomenon, especially in post-stall where the flow is highly nonlinear. Computational …

Bird flight incorporates complex multi-degree-of-freedom motions, such as flapping, pitching,
twisting, and folding. The aerodynamic mechanism of these complex movements, especially …

The flow-induced vibration of a NACA 0015 airfoil model with pitch and plunge degrees of

In this study, the dynamic stall evolutions were investigated using particle image velocimetry
(PIV) in a water channel with Reynolds number Re= 4.5× 10 3 based on the chord length …

Measuring the aerodynamic loads on dynamic objects in small wind tunnels is often
challenging. In this regard, fast-response particle image velocimetry (PIV) data are post …

The generation of smooth, symmetric, and periodic gust disturbances in an experimental
context is demonstrated using a single oscillating airfoil. A pitching and plunging symmetric …

Quantitative evaluation of time dependent flow structures around and in the near-wake of an
oscillating airfoil is investigated using the Digital Particle Image Velocimetry (DPIV) …
