The topic of this article is a review of the approach to extract pressure fields from flow
velocity field data, typically obtained with particle image velocimetry (PIV), by combining the …

In a large variety of fluid-dynamic problems, it is often impossible to directly measure the
instantaneous aerodynamic or hydrodynamic forces on a moving body. Examples include …

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

We describe and characterize a method for estimating the pressure field corresponding to
velocity field measurements such as those obtained by using particle image velocimetry …

Experiments on leading-edge vortex (LEV) growth and detachment from a plunging profile
have been conducted in a free-surface water tunnel. Direct-force and velocity-field …

Small unmanned aerial vehicles and biological fliers can experience wind gusts of similar
magnitude to the flight speed, which is detrimental to flight stability. For one encounter type …

Experiments with a pitching and plunging airfoil are conducted in order to investigate the
mechanisms responsible for the formation and detachment of leading edge vortices (LEVs) …

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 …

While studies on unsteady airfoils in a uniform free stream are abundant, the quest for
efficient man-made propulsion and energy harvesting calls for an improved understanding …

In the present study the power extraction capability by flapping foil hydrokinetic turbine is
investigated. The heaving motion of the foil is considered in two different motion patterns …
