Kármán vortex street in a two-component Bose–Einstein condensate
Vortex shedding from a moving obstacle potential in a two-component Bose–Einstein condensate is investigated numerically. For a miscible two-component condensate composed of ^23 Na and ^87 Rb atoms, in the wake of obstacle, the Kármán vortex street is ...

A non-linear observer for unsteady three-dimensional flows [PDF]
A method is proposed to estimate the velocity field of an unsteady flow using a limited number of flow measurements. The method is based on a non-linear low-dimensional model of the flow and on expanding the velocity field in terms of empirical basis ...

Effect of NACA0012 Airfoil Pitching Oscillation on Flow Past a Cylinder
The flow past a cylinder is a classical problem in flow physics. In a certain range of Reynolds number, there will be Karman vortex street phenomenon in the wake of a cylinder, which will greatly increase the pressure drag of the cylinder. By controlling
