Elliptical vortex necklaces in Mathieu lattices

Physical Review A, 2018
We demonstrate unusual kinds of discrete vortex beams, elliptical necklaces, realized by Mathieu photonic lattices. Varying the order of the Mathieu lattices and their ellipticity, we can control the shape and size of such necklaces. Besides stable vortex states, we observe oscillatory dipole states or dynamical instabilities and study their orbital ...

Quantitative characteristics of a laminar, unsteady necklace vortex system at a rectangular block-flat plate juncture

Journal of Fluid Mechanics, 1995
The unsteady laminar necklace vortex system formed at the junction of a rectangular bluff body and a flat plate was studied experimentally using hydrogen bubble flow visualization and particle image velocimetry (PIV). The vortex system was found to exhibit unsteady behaviour similar to that described by other investigators for cylinder-flat plate ...

Development of a cylindrical-blade wind turbine driven by a necklace vortex

When the blade of a horizontal-axis wind turbine is replaced with a circular cylinder and a ring plate is installed downstream, a necklace vortex forms at their intersection. As the cylinder rotates, this vortex remains stationary on the opposite side of its motion, generating lift and driving the turbine.
