Review of the excitation mechanism and aerodynamic flow control of vortex-induced vibration of the main girder for long-span bridges: A vortex-dynamics approach

Journal of Fluids and Structures, 2021
Two vortex-induced vibration (VIV) events of the main girder of long-span bridges successively happened on the Yingwuzhou suspension bridge and Humen suspension bridge in China, 2020, and drew public attention. Especially for the Humen suspension bridge,

Vortex dynamics and hydrodynamic performance enhancement mechanism in batoid fish oscillatory swimming

Journal of Fluid Mechanics, 2021
The effects of chordwise deformation and the half-amplitude asymmetry on the hydrodynamic performance and vortex dynamics of batoid fish have been numerically investigated, in which the two parameters were represented by the wavenumber ($W$) and the ...

Vortex dynamics for flow around the slat cove at low Reynolds numbers

Journal of Fluid Mechanics, 2021
Time-resolved particle image velocimetry (TR-PIV) is employed to investigate the vortex dynamics around the slat cove of a 30P30N multi-element airfoil at a fixed geometric angle of attack of 4 ° within the stowed chord Reynolds number range of 9.3 × 103

Vortex-sink dynamics

Physical Review E, 1996
Interaction of a point vortex sink (twister) with an obstacle in a stationary and nonstationary flow is considered. Classification of twister trajectories, depending on nondimensional parameters of the system, and the probability of twister-obstacle collisions are presented.

Effects of vortex dynamics mechanism of blade-end treatment on the flow losses in a compressor cascade at critical condition

, 2020
Elucidating the underlying mechanism of the vortex dynamics in compressors is essential for determining the sources of the flow losses in compressor cascades. Hence, the effects of blade-end treatments on a linear compressor cascade should be analyzed at

Coupling Myocardium and Vortex Dynamics in Diverging-Wave Echocardiography

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2019
Echocardiography is widely used to provide critical left ventricular indices describing myocardial motion and blood inflow velocity. Tissue motion and blood flow are strongly connected and interdependent in the ventricle. During cardiac relaxation, rapid
