Dissipative flow and vortex shedding in the Painlev\'e boundary layer of a Bose Einstein condensate
, 2003 Raman et al. have found experimental evidence for a critical velocity under which there is no dissipation when a detuned laser beam is moved in a Bose-Einstein condensate. We analyze the origin of this critical velocity in the low density region close to

An experimental study of airfoil-spoiler aerodynamics [PDF]
The steady/unsteady flow field generated by a typical two dimensional airfoil with a statically deflected flap type spoiler was investigated. Subsonic wind tunnel tests were made over a range of parameters: spoiler deflection, angle of attack, and two ...

Transition in vortex wakes of flow around an elliptic cylinder
Archives of MechanicsTransition in the wake flow around an elliptic cylinder was numerically investigated at Reynolds numbers (Re) ranging from 3 to 200. The cylinder axis ratio (AR) varies from 0.125 to 8, while its angle of attack (AoA) was examined at 30°, 60°, and 90 ...

Development of the wake behind a circular cylinder impulsively started into rotatory and rectilinear motion: Intermediate rotation rates [PDF]
The temporal development of two-dimensional viscous incompressible flow generated by a circular cylinder started impulsively into steady rotatory and rectilinear motion is studied by integration of a velocity/vorticity formulation of the governing ...

The Generation Mechanism of the Flow-Induced Noise from a Sail Hull on the Scaled Submarine Model
Applied Sciences, 2018 Flow-induced noise from the sail hull, which is induced by the horseshoe vortex, the boundary layer separation and the tail vortex shedding, is a significant problem for the underwater vehicles, while has not been adequately studied.
