Active Control Of Flow-induced Vibration
Journal of Sound and Vibration, 1993Abstract The active control of flow-induced oscillations, specifically, vortex-induced oscillations of circular cylinders and galloping oscillations of circular cylinders and galloping oscillations of a square prism, are considered. In the case of vortex-induced oscillations, the vibrating cylinder is modeled as a single-degree-of-freedom (sdof ...

Evolving strategies for active flow control
Proceedings of the 2000 Congress on Evolutionary Computation. CEC00 (Cat. No.00TH8512), 2002Rechenberg and Schwefel (Rechenberg, 1994) came up with the idea of evolution strategies for flow optimization. Since then advances in computer architectures and numerical algorithms have greatly decreased computational costs of realistic flow simulations, and today computational fluid dynamics (CFD) is complementing flow experiments as a key guiding ...

Electrohydrodynamic flow for the active control of gas flows
Uspekhi Fizicheskih Nauk, 2017Abstract A new approach to producing powerful electrohydrodynamic flows in a gas environment is discussed, in which a barrier discharge distributed over a dielectric surface is used as an intense ion source. Electric discharge systems for active control of gas flows with a high (> 15 l s−1) volumetric rate are developed and ...

This paper considers the two-dimensional problem of a plane vortex sheet disturbed by an impulsive line source. A previous incorrect treatment of this problem is examined in detail. Instabilities of the vortex sheet are triggered by the source and grow exponentially in space and time.
