Prediction method of hydrofoil vortex shedding frequency at high Reynolds numbers
Zhongguo Jianchuan Yanjiu, 2019 [Objectives] Flow around hydrofoils under high Reynolds number is always a hot topic in hydrodynamic field due to its complicated principle and difficult calculation. The Discrete Vortex Model (DVM) based on vorticity and stream function formulation is a

Vortex shedding in a model of superflow [PDF]
Physica D: Nonlinear Phenomena, 1999 The present article represents part of the PhD. dissertation by C. Josserand. We discuss the nucleation of quantized vortices in the nonlinear Schrödinger equation (NLS) for a flow around a disk in two spatial dimensions. It appears that the vortices are nucleated when the flow becomes locally (at the edge of the disk) supersonic.

Lock-in of the vortex-induced vibrations of a long tensioned beam in shear flow [PDF]
, 2011 The occurrence of lock-in, defined as the local synchronization between the vortex shedding frequency and the cross-flow structural vibration frequency, is investigated in the case of a tensioned beam of length to diameter ratio 200, free to move in both

Control Of Vortex Shedding From A Square Cylinder [PDF]
, 2008 Small circular, square, and thin-strip cross-sectional elements are used to suppress vortex shedding from a square cylinder at Reynolds numbers in the range of 1.12 x 10(4)-1.02 x 10(5). The axes of the element and cylinder are parallel.

Kármán vortex street in a two-component Bose–Einstein condensate
New Journal of Physics, 2019 Vortex shedding from a moving obstacle potential in a two-component Bose–Einstein condensate is investigated numerically. For a miscible two-component condensate composed of ^23 Na and ^87 Rb atoms, in the wake of obstacle, the Kármán vortex street is ...
