Periodic shedding of vortex dipoles from a moving penetrable obstacle in a Bose-Einstein condensate
, 2015 We investigate vortex shedding from a moving penetrable obstacle in a highly oblate Bose-Einstein condensate. The penetrable obstacle is formed by a repulsive Gaussian laser beam that has the potential barrier height lower than the chemical potential of ...

Insights into Vortex Shedding with Data Analysis
Journal of Fluid Science and Technology, 2009 Unsteady, three-dimensional characteristics of vortex shedding were studied with self-made MEMS sensors situated spanwisely on a circular cylinder subjected to uniform incoming flow. Firstly, verification on the reliability of the MEMS sensor signals was

Global modes and nonlinear analysis of inverted-flag flapping [PDF]
, 2017 An inverted flag has its trailing edge clamped and exhibits dynamics distinct from that of a conventional flag, whose leading edge is restrained. We perform nonlinear simulations and a global stability analysis of the inverted-flag system for a range of ...

Von K\'arm\'an vortex street in a Bose-Einstein condensate
, 2010 Vortex shedding from an obstacle potential moving in a Bose-Einstein condensate is investigated. Long-lived alternately aligned vortex pairs are found to form in the wake, as for the von K\'arm\'an vortex street in classical viscous fluids.
