Modulation of a quantized vortex street with a vibrating obstacle    [PDF]

Hiroki Saito, Kenta Tazaki, Tomohiko Aioi
Dynamics of a superfluid flow past an obstacle are investigated by solving the Gross-Pitaevskii equation numerically. For an appropriate velocity and size of the obstacle, quantized vortices are periodically generated in the wake, which form a Benard-von Karman vortex street. It is found that vibration of an obstacle modulates the vortex street breaking a symmetry.
