Effect of Flexibility on the Motion State of Filament in Vortex Streets
Hangkong gongcheng jinzhan, 2022 In vortex streets,the motion state of filaments is closely related to its propulsion performance. Studying the influence of flexibility on the motion state of filaments in vortex streets can provide reference for flexible design of flexible aircraft in ...

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 ...

Detailed Wake Structure behind an Elastic Airfoil
Journal of Fluid Science and Technology, 2009 An unsteady flow in a low Reynolds number region attracts attention in recent years. The authors measured vortex flow in the wake of the rigid flat plate, rigid NACA0010, elastic flat plate and elastic NACA0010 with heaving motions and evaluated ...

Periodic Vortex Streets and Complex Monodromy [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2012 The explicit constructions of periodic and doubly periodic vortex relative equilibria using the theory of monodromy-free Schrödinger operators are described. Several concrete examples with the qualitative analysis of the corresponding travelling vortex streets are given.

Mechanism of momentum transportation in the intermediate wake of a heated cylinder
Nihon Kikai Gakkai ronbunshu, 2020 Measurements in the wake of a heated cylinder are made by a thermo-anemometer. The purpose is to make clear the effects of buoyancy of heated cylinder on the mechanism of momentum transportation in the wake.
