Sanderson first coined the term, “Vile Vortices”1 in his article “The Twelve Devil’s Graveyards Around the World” (Saga magazine, 1972). The best-known Vile Vortices are the Bermuda Triangle, the Dragon’s Triangle (Devil's Sea), and the South Atlantic Anomaly. However, each of ...
This quantity is also known as the circulation around the line, so at an instant of time a vortex tube has a unique value of the circulation applying to all cross sections (see illustration). Vortex tube; &ohgr; is the vorticity Vortex lines confined to a layer rather than a tube ...
The vortex center moves around the bubble, as has been shown before for the case where rotation of the bubble is absent18,19, with the position of the center of the vortex, Fig. 2a, showing several turns and wobbles. Rotation of the cell introduces a global movement of the bubble and ...
each towards its own side, at a speed of around 2 to 3 kt. It is this phenomenon, when associated with a light crosswind component that tends to “hold” the “into wind” vortex roughly on the centreline, whilst the “downwind” vortex moves away...
Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research ...
However, there's always been a bit of a paradox at the heart of this theory: If the environment immediately around black holes is adept at removing material from danger, how are supermassive black holes able to feed on enough matter to grow to their gargantuan masses of millions or even ...
Asymptotic behavior of 2D incompressible ideal flow around small disks We prove that the homogenization limit retains information on the circulations as a time-independent coefficient. More precisely, we assume that: (1) \\... C Lacave,MCL Filho,HJN Lopes - 《Mathematics》 被引量: 14发表: 20...

which wraps around the inboard region of the wing. The footprint of the horseshoe vortex on the surface is also seen in the oil flow visualisation in Fig.2aand its origin is depicted in the centre of Fig.3. In Fig.3b, the foci in the dorsal separation region show the emergence of a...
