Computation of Trailing Edge Noise with a Discontinuous Galerkin Method [PDF]

, 2008
Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Pertur- bation Equations (APE), which are employed as governing equations, are discretized via a ...

A multi-objective and CFD based optimization of roof-flap geometry and position for simultaneous drag and lift reduction

Propulsion and Power Research
As the transport sector is responsible for the consumption of a vast proportion of the oil produced, it is mandatory to research feasible solutions to tackle this issue.

A modification of Amiet's classical trailing edge noise theory for strictly two dimensional flows

, 2007
The aim of this report is to derive theoretical expressions for the far-field pressure generated by disturbances convecting over a trailing edge. First, a general calculation of thefar-field pressure is discussed.
