The Atmospheric Vortex Streets and Their Impact on Precipitation in the Wake of the Tibetan Plateau
Atmosphere, 2023 Atmospheric vortex streets (AVSs) are often observed in the wake of the leeward side of mountainous islands and are considered atmospheric analogs of the classic Kármán vortex street when a fluid flows past a cylindrical obstacle.

Vortex dynamics on a cylinder [PDF]
, 2002 Point vortices on a cylinder (periodic strip) are studied geometrically. The Hamiltonian formalism is developed, a non-existence theorem for relative equilibria is proved, equilibria are classified when all vorticities have the same sign, and several ...

Soliton Instabilities and Vortex Streets Formation in a Polariton Quantum Fluid [PDF]
, 2011 Exciton-polaritons have been shown to be an optimal system in order to investigate the properties of bosonic quantum fluids. We report here on the observation of dark solitons in the wake of engineered circular obstacles and their decay into streets of ...

On the linear stability of the inviscid Kármán vortex street [PDF]
, 1987 The classical point-vortex model for a Kármán vortex street is linearly stable only for an isolated case. This property has been shown numerically to hold for other, more complicated, models of the same flow.

The Interaction Vortex Flow Around Two Bluff Cylinders
EPJ Web of Conferences, 2013 In this study, the interaction vortex flow features around a pair of parallel arranged bluff cylinders were observed by visualizing water flow experiment at the range of the gap ratio G/d=0~3.

The linear two-dimensional stability of inviscid vortex streets of finite-cored vortices [PDF]
, 1984 The stability of two-dimensional infinitesimal disturbances of the inviscid Karman vortex street of finite-area vortices is reexamined. Numerical results are obtained for the growth rate and oscillation frequencies of disturbances of arbitrary ...

Properties of a Vortex Street of Finite Vortices [PDF]
SIAM Journal on Scientific and Statistical Computing, 1981 Steady solutions of the Euler equations are calculated for an infinite array of vortices, consisting of two staggered parallel rows of identical vortices of finite area and uniform vorticity. These models are similar to the “vortex streets” studied theoretically by von Karman and others, except that here vortices of finite rather than infinitesimal ...
