Journal ArticleDOI
Vortex shedding suppression and wake control: A review
TL;DR: In this article, a survey of existing studies on different methods of controlling the wake destructive behavior and suppression of vortex shedding behind bluff bodies are discussed, including the very recent developments, and the effectiveness of each technique on the drag reduction.
Feedback control of vortex shedding from a circular cylinder at low reynolds numbers
TL;DR: In this paper, an experimental study on the suppressing of vortex shedding from a circular cylinder by feedback sound was performed in a wind tunnel, and the feedback sound is generated inside the cylinder and locally introduced into the flow through a thin slit on the cylinder surface.
Journal ArticleDOI
Active flow control of vortex induced vibrations of a circular cylinder subjected to non-harmonic forcing
TL;DR: In this article, a simple momentum injection based active flow control strategy was proposed to suppress vortex induced oscillations at low Reynolds numbers, where two small control cylinders behind the main cylinder played the role of actuators, enforcing the desired momentum injection.

Mitigating vortex-induced vibration by acceleration feedback control
Joy Mondal,S. Chatterjee +1 more
TL;DR: In this article, the performance of the acceleration feedback control is compared with that of the simple passive vibration absorber and the effect of time-delay in the feedback loop is also investigated.

The effect of externally applied rotational oscillations on FIV characteristics of tandem circular cylinders for different spacing ratios
TL;DR: In this paper, an active control strategy for attenuation of in-line and transverse flow-induced vibration (FIV) of two tandem-arranged circular cylinders is explored.
