Effects of leading-edge separation on the vortex shedding and aerodynamic characteristics of an elongated bluff body

Journal of Wind Engineering and Industrial Aerodynamics, 2020
Wind-tunnel experiments were conducted on an elongated bluff body to investigate the effects of leading-edge separation on its vortex shedding and aerodynamic characteristics.

Control of Leading-Edge Vortex Breakdown by Trailing Edge Injection

Journal of Aircraft, 1999
The goal of this research is the control of the vortex breakdown locations over sharp-edged, slender, delta wings at high angles of attack. Water tunnel tests of a 75-deg delta wing examined symmetric and asymmetric trailing-edge jet injection as a method to control and delay the leading-edge vortex breakdown locations. These tests were accomplished at

Multiple inviscid solutions for the flow in a leading-edge vortex

AIAA Journal, 2000
To analyze the flowfield inside the vortex formed at the leading edge of a highly swept wing at an angle of attack, conical similarity solutions of the compressible Euler equations have been obtained and compared to incompressible conical similarity flow solutions.

Leading-edge vortex enhancement of a flexible flapping wing with the clap-and-fling mechanism

The Physics of Fluids
The clap-and-fling mechanism, initially discovered in insect flight, has been widely adopted in Flapping-Wing Micro Air Vehicle (FWMAV) designs to enhance their lift generation.

A multi‐vortex model of leading‐edge vortex flows

International Journal for Numerical Methods in Fluids, 1983
AbstractA multi‐vortex model of the vortex sheets shed from the sharp leading edges of slender wings is considered. The method, which is developed within the framework of slender‐body theory, is designed to deal with those situations in which more than one centre of rotation is formed on the wing, for example on a slender wing with lengthwise camber or
