An experimental study of airfoil-spoiler aerodynamics [PDF]

open access: yes
The steady/unsteady flow field generated by a typical two dimensional airfoil with a statically deflected flap type spoiler was investigated. Subsonic wind tunnel tests were made over a range of parameters: spoiler deflection, angle of attack, and two ...

Master-modes in 3D turbulent channel flow [PDF]

open access: yes, 2008
Turbulent flow fields can be expanded into a series in a set of basic functions. The terms of such series are often called modes. A master- (or determining) mode set is a subset of these modes, the time history of which uniquely determines the time ...
