Effect of NACA0012 Airfoil Pitching Oscillation on Flow Past a Cylinder

open access: yesEnergies, 2021
The flow past a cylinder is a classical problem in flow physics. In a certain range of Reynolds number, there will be Karman vortex street phenomenon in the wake of a cylinder, which will greatly increase the pressure drag of the cylinder. By controlling

Spatio-temporal stability of the Karman vortex street and the effect of confinement [PDF]

open access: yes, 2016
The instability of the Karman vortex street is revisited under a spatio-temporal perspective that allows the taking into account of the advection of the vortices by the external flow.

Numerical Investigation on the Effect of Asymmetry of Flow Velocity on the Wake Vortex of Hydrofoils

open access: yesJournal of Marine Science and Engineering, 2022
The Karman vortex street is a common flow phenomenon. In hydraulic machinery, it is usually located downstream of the guide vanes and the runner blades, which reduces hydraulic performance and may also cause fatigue damage to the structure.

The characteristics of a Karman vortex street in a channel of finite breadth [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1928
Abstract It is well known that the classical potential flow of a perfect fluid past a bluff body is not a satisfactory representation of the actual flow, and that, in particular, it fails to give any indication of the resistance or drag which is experienced by the body.

Low-Frequency Modulation of Turbulent Karman Vortex Street.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1996
A wavelet analysis using the Morlet wavelet is applied to show the existence of low-frequency modulation in the velocity fluctuation in the turbulent vortex street wake of a circular cylinder at a Reynolds number of 5000. The central frequency of the low-frequency modulation fm is 1/30-1/20 times the frequency of vortex shedding from the circular ...
