Vortex shedding from tapered, triangular plates: taper and aspect ratio effects [PDF]

open access: yes, 2004
Further experiments on features of the vortex shedding from tapered flat plates normal to an airstream are described. The work extends that of Castro and Rogers (2002) and concentrates on the study of the effects of varying the spanwise aspect ratio for ...

Investigation of Fractal Characteristics of Karman Vortex for NACA0009 Hydrofoil

open access: yesFractal and Fractional, 2023
A Karman vortex is a phenomenon of fluid flow that can cause fluctuation and vibration. As a result, it leads to fatigue damage to structures and induces safety accidents.

Investigation into the Strouhal numbers associated with vortex shedding from parallel-plate thermoacoustic stacks in oscillatory flow conditions [PDF]

open access: yes, 2010
This paper investigates vortex shedding processes occurring at the end of a stack of parallel plates, due to an oscillating flow induced by an acoustic standing wave.

Vortex-induced vibrations of a long flexible cylinder in shear flow [PDF]

open access: yes, 2010
We investigate the in-line and cross-flow vortex-induced vibrations of a long cylindrical tensioned beam, with length to diameter ratio L/D = 200, placed within a linearly sheared oncoming flow, using three-dimensional direct numerical simulation.

Application of lattice constructions for protection of high-rise chimneys from vortex shedding [PDF]

open access: yesE3S Web of Conferences
Consideration of vortex shedding response is important for high-rise chimneys when air flow causes strong vibrations of the structure in a certain range of wind speeds when the frequency of natural vibrations of the structure coincides with the frequency

Numerical Assessment of Flow Energy Harvesting Potential in a Micro-Channel

open access: yesFluids, 2023
A micro-energy harvesting device proposed in the literature was numerically studied. It consists of two bluff bodies in a micro-channel and a flexible diaphragm at its upper wall.

Coupling Between Thermal Oscillations in the Surface of a Micro-Cylinder and Vortex Shedding [PDF]

open access: yes, 2007
his article studies the coupling between prescribed thermal oscillations in the surface of a micro-cylinder and vortex shedding. We deal with the unsteady, laminar, compressible flow regime where the aerodynamics forces have a periodic behavior.

A numerical study of an inline oscillating cylinder in a free stream [PDF]

open access: yes, 2011
Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Visualization and Parametric Study on Vortex Shedding Suppression of Cylindrical Structures in Offshore Engineering Using Large Eddy Simulation

open access: yesJournal of Marine Science and Engineering, 2023
Cylindrical structures are widely used in offshore and marine engineering, but they may suffer from vortex-induced vibration under the influence of ocean or wave currents, which can lead to severe fatigue damage. In this study, we applied the open-source

Wake states and frequency selection of a streamwise oscillating cylinder [PDF]

open access: yes, 2013
This paper presents the results of an in-depth study of the flow past a streamwise oscillating cylinder, examining the impact of varying the amplitude and frequency of the oscillation, and the Reynolds number of the incoming flow.
