A study is made of the laminar flow in the neighbourhood of the trailing edge of an aerofoil at incidence. The aerofoil is replaced by a flat plate on the assumption that leading-edge stall has not taken place. It is shown that the critical order of magnitude of the angle of incidence α* for the occurrence of separation on one side of the plate is ...

Effects of Gurney flap and trailing-edge wedge on a blunt trailing-edge aerofoil
International Conference on Renewable Power Generation (RPG 2015), 2015Gurney flap and trailing-edge wedge are useful devices to improve the aerodynamic performance of aerofoils for wind turbines; however, the researches on blunt trailing-edge aerofoil are limited. In this paper, we focus on the flow mechanism of Gurney flaps and trailing-edge wedges and their impacts on a blunt trailing-edge aerofoil DU97-W-300.

The last thirty years has seen incredible growth in the computer industry, both commercial and technological. However, during that same period, there have been various studies asserting that somewhere between sixty and eighty percent of all software projects fail and the blame for these failures is most often laid at the door of the project manager or ...

Journal of Fluid Mechanics, 1969
The flow is examined in the neighbourhood of the trailing edge of slender aerodynamic shapes which terminate in either a cusp or a wedge. The manner in which the boundary layer reacts to the rapidly varying pressure field in such regions is analyzed using the method of matched asymptotic expansions. The case of a wedge is examined in greater detail and

Aircraft Engineering and Aerospace Technology, 1937
THE reader who asks for more wood and less trees in technical discussions of wing flaps has my sympathy, since I have myself been responsible for some denseness of undergrowth. In this article 1 intend to avoid detail somewhat ruthlessly, to stand back and get a long view of the subject, to give, in fact, a freehand sketch rather than a blue print.

A Trailing-Edge Noise Model for Serrated Edges
21st AIAA/CEAS Aeroacoustics Conference, 2015© 2016, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved. This paper is concerned with the development of a theoretical model for the prediction of the sound radiated by serrated trailing-edges. The proposed model is based on Fourier expansion and Amiet's formulation.

The Aeroacoustics of Trailing Edges
1989Trailing edge sound is an aeroacoustic phenomenon which contributes to the noise from lifting surface flaps, rotating machines and certain turbulent nozzle flows. Part I of this paper is a survey which describes the physics of aerodynamic sound generation by trailing edge flows; it is particularly relevant to lifting surfaces.

The Quarterly Journal of Mechanics and Applied Mathematics, 1998
Summary: The structure of the flowfield in the vicinity of the trailing edge of a flat plane at zero incidence in mixed transonic flow has been studied using viscous-inviscid interaction methods. The resulting nonlinear partial differential equations governing the flow were solved numerically using finite-difference methods for a range of values of a ...

Trailing-edge region of airfoils
Journal of Aircraft, 1989Measured and calculated results obtained in a set of trailing-edge flows are examined to consolidate understanding of the requirements and implications for airfoil calculation methods. The experiments investigated sharp, round, and blunt trailing edges, attached and separated turbulent boundary layers, and boundary-layer interaction with the wake of an

Sound diffraction at a trailing edge
Journal of Fluid Mechanics, 1981The diffraction of externally generated sound in a uniformly moving flow at the trailing edge of a semi-infinite flat plate is studied. In particular, the coupling of the sound field to the hydrodynamic field by way of vortex shedding from the edge is considered in detail, both in inviscid and in viscous flow.In the inviscid model the (two-dimensional)
