We report on the dynamics of the formation and growth of the leading-edge vortex and the
corresponding unsteady aerodynamic torque induced by large-scale flow-induced …

In nature, birds and insects usually execute pitch-up maneuvers, which is either an active
perching or a passive response against gusts. During such maneuvers, their wings flap with …

While landing, birds often perform a perching maneuver, which involves pitching their wings
upward while decelerating to a complete stop. This study is motivated by the observation …

We examine the dynamics of the leading-edge vortex (LEV) on a rapidly pitching plate with
the aim of elucidating the underlying flow physics that dictates the stability and circulation of …

Impulsively started, low-aspect-ratio elliptical flat plates have been investigated
experimentally to understand the vortex pinch-off dynamics at transitional and fully turbulent …

Impulsively started, low-aspect-ratio elliptical and rectangular flat plates were investigated to
determine the role of geometric asymmetries on vortex evolution. Dye visualizations, force …

As a canonical problem, the impulsive starting of a circular disk contains the fundamental
mechanisms of the force generation of the drag-based propulsions. In this paper, a circular …

The vortical structures over a thin rectangular wing with a very low aspect ratio of 0.277 were
investigated in a wind tunnel at an effective Reynolds number of. When applying pitch-up …

A low-order model for the circulation budget within a leading-edge vortex (LEV) is proposed,
based on one-dimensional species advection. The model is composed of two parts: first, a …

An investigation into the influence of seemingly analogous kinematics (plunge versus tow)
for rapidly accelerating, low-aspect-ratio plates has been performed. The instantaneous …
