The leading-edge vortex of swift wing-shaped delta wings [PDF]
Royal Society Open Science, 2017 Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the leading-edge vortex (LEV) for lift generation in a variety of flight conditions.

Leading-edge vortex dynamics on plunging airfoils and wings [PDF]
Journal of Fluid Mechanics, 2022 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 simulations, and stability analysis in order to understand the deformation ...

Leading edge vortex in a slow-flying passerine [PDF]
Biology Letters, 2012 Most hovering animals, such as insects and hummingbirds, enhance lift by producing leading edge vortices (LEVs) and by using both the downstroke and upstroke for lift production. By contrast, most hovering passerine birds primarily use the downstroke to generate lift.

, 2015 Leading edge vortices can create high local pressures which in some situations may be advantageous but in others may cause damage. This paper looks at three wind engineering situations: windborne debris, roof suctions on a low-rise building and pressures

Coriolis effect and the attachment of the leading edge vortex [PDF]
Journal of Fluid Mechanics, 2017 The role of the Coriolis effect on the attachment of the leading edge vortex (LEV) is investigated. Toward that end, the Navier–Stokes equations are solved in the non-inertial reference frame of a high angle of attack $\unicode[STIX]{x1D6FC}$ rotating wing with the Coriolis term being artificially tuned.

Scaling trends of bird's alular feathers in connection to leading-edge vortex flow over hand-wing. [PDF]
Sci Rep, 2020 An aerodynamic structure ubiquitous in Aves is the alula; a small collection of feathers muscularized near the wrist joint. New research into the aerodynamics of this structure suggests that its primary function is to induce leading-edge vortex (LEV ...

A species-transport model for circulation in a leading-edge vortex [PDF]
Advances in Aerodynamics, 2022 In this study, we propose a model to predict circulation growth along the span of a rotating wing, in which circulation transport is represented as species transport.
