A Novel Airframe Design Methodology For Silent Aircraft [PDF]

open access: yes, 2008
The impact of noise on civil aviation is not just a localised airport problem, but a global concern, due to the ever-increasing demands for passenger travel.

The finite element method in low speed aerodynamics

open access: yes, 1975
The finite element procedure is shown to be of significant impact in design of the 'computational wind tunnel' for low speed aerodynamics. The uniformity of the mathematical differential equation description, for viscous and/or inviscid, multi ...

INDUSTRIAL CFD SIMULATION OF AERODYNAMIC NOISE

open access: yes, 2008
Real challenges to suppress undesirable fluid-excited acoustics are posed by a wide variety of engineering disciplines. Noise regulations, passenger comfort and component stability are motivators which are continuing to stimulate substantial efforts ...

The aerodynamics of curved jets and breakaway in Coanda flares [PDF]

open access: yes, 1991
An investigation was carried out into external-Coanda Effect flares designed by British Petroleum International plc. The phenomenon of interest was breakaway of an under expanded axisymmetric curved wall jet from the guiding surface due to high blowing ...

Experimental aeroacoustics study on jet noise reduction using tangential air injection

open access: yes, 2011
PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...

Flow Feature Aligned Mesh Generation and Adaptation [PDF]

open access: yes, 2013
Methods which allow for construction of flow feature aligned meshes in two- and three-dimensions have been developed in this thesis to investigate their potential for improvements in the numerical solution relative to globally refining the mesh.

Flow Characteristics Over a Missile at Higher Angle of Attacks using Experiments and Simulation

open access: yes, 2018
The need to determine forces and moments acting on bodies of revolution at high angles of attack originally arose in connection with airships. In general missile aerodynamics is dominated with vertical and separated flows.
