Effect of Wavy Leading Edges on Airfoil Trailing-Edge Bluntness Noise
Aerospace, 2023 Among the several noise-generation mechanisms of airfoil self-noise, trailing-edge bluntness noise is an important noise source, which is caused by the vortex shedding at blunt trailing edges.

Leading-edge vortex shedding from rotating wings [PDF]
Fluid Dynamics Research, 2014 The paper presents a numerical investigation of the leading-edge vortices generated by rotating triangular wings at Reynolds number $Re=250$. A series of three-dimensional numerical simulations have been carried out using a Fourier pseudo-spectral method with volume penalization.

A species-transport model for circulation in a leading-edge vortex
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.

CORIOLIS KEEPS LEADING EDGE VORTEX IN PLACE [PDF]
Journal of Experimental Biology, 2009 ![Figure][1] Flies may not have the nicest of personal habits, but no one can fail to be amazed by their remarkable agility as they twist, turn and hover in the air. And their manoeuvrability has not escaped the notice of aeronautic engineers; they'd love to design a minute flying ...
