Vortex flow generator utilizing synthetic jets by diaphragm vibration [PDF]
, 2018 This paper develops a millimeter scale fully packaged device in which a vortex flow of high velocity is generated inside a chamber. Under the actuation by a lead zirconate titanate (PZT) diaphragm, a flow circulates with increasing velocity after each ...

Generation of Nonlinear Vortex Precursors
Physical Review Letters, 2016 We numerically study the propagation of a few-cycle pulse carrying orbital angular momentum (OAM) through a dense atomic system. Nonlinear precursors consisting of high-order vortex har- monics are generated in the transmitted field due to ultrafast Bloch oscillation.

Plasmonic vortex generator without polarization dependence
New Journal of Physics, 2018 In view of the limitations of vortex generators with polarization dependence at present, we propose a plasmonic vortex generator composed of rectangular holes etched in silver film, in which the optical vortex can be generated under arbitrary linearly ...

Regimes of flow past a vortex generator [PDF]
, 2012 A complete parametric investigation of the development of multi-vortex regimes in a wake past simple vortex generator has been carried out. It is established that the vortex structure in the wake is much more complicated than a simple monopole tip vortex.
