Vortex suppression and drag reduction in the wake of counter-rotating cylinders
drag reduction instability control vortex interactions
2015/7/3
The flow over a pair of counter-rotating cylinders is investigated numerically and experimentally. It is demonstrated that it is possible to suppress unsteady vortex shedding for gap sizes from ...
Suppression of the unsteady vortex wakes of a circular cylinder pair by a doublet-like counter-rotation
vortex wakes instabilities vortex suppression numerical simulation virtual elliptic body fl ow control

The present investigation examines the suppression of unsteady, two-dimensional wake instabilities of a pair of identical circular cylinders, placed side-by-side normal to freestream at a low Reynolds...
Suppression of vortex-induced forces on a two-dimensional circular cylinder by a short and thin splitter plate interference
circular cylinder splitter plate interference
2015/6/23
This paper briefly reviews bluff body aerodynamics and focuses mainly on
the use of short and thin splitter plates to interfere with the vortex wakes and
suppress vortex-induced forces (VIF). The ...

The present investigation examines the suppression of unsteady, two-dimensional wake
instabilities of a pair of identical circular cylinders, placed side-by-side normal to freestream

Recent developments in actuator technology have resulted in small, simple flow control devices capable of
affecting the flow field over flight vehicles sufficiently to generate control forces. One o...
Flutter Suppression for High Aspect Ratio Flexible Wings Using Microflaps
Wings Using Microfl aps Microflaps
2015/6/18
Miniature trailing edge effectors (MiTEs) are small
flaps (typically 1% to 5% chord) actuated with deflection angles up to 90 degrees. Because of their
small size, these devices pr...
