Modelling vortex-vortex and vortex-boundary interaction
The motion of two-dimensional inviscid, incompressible fluid with regions of constant vorticity is studied for three classes of geophysically motivated problem. First, equilibria consisting of point vortices located near a vorticity interface generated by a shear flow are found analytically in the linear (small-amplitude) limit and then numerically for the fully nonlinear problem. The equilibri...
متن کاملVortex waistlines and vortex gas
A large body of work over the last few years [1] supports the picture of long thick vortices as the most important long range degrees of freedom for confinement. In this note we wish to examine more closely the manner in which a linear potential arises from vortex fluctuations. One customarily assumes a picture of randomly distributed vortices of certain thickness and basically arbitrary length...
متن کاملVortex–Vortex Interactions in the Winter Stratosphere
This paper examines the interaction of oppositely signed vortices in the compressible (non-Boussinesq) quasigeostrophic system, with a view to understanding vortex interactions in the polar winter stratosphere. A series of simplifying approximations leads to a two-vortex system whose dynamical properties are determined principally by two parameters: the ratio of the circulation of the vortices ...
متن کاملControlling vortex motion and vortex kinetic friction
We summarize some recent results of vortex motion control and vortex kinetic friction. (1) We describe a device [J.E. Villegas, S. Savel’ev, F. Nori, E.M. Gonzalez, J.V. Anguita, R. Garcı̀a, J.L. Vicent, Science 302 (2003) 1188] that can easily control the motion of flux quanta in a Niobium superconducting film on an array of nanoscale triangular magnets. Even though the input ac current has zer...
متن کاملAbout Vortex Physics and Vortex Losses
As quantum physics nowadays tries to reframe and explain electric and magnetic field phenomena, we must not be mislead over the fact that quantum physics remains a “stepdaughter” of field physics based solely on postulates until eventually it will have found a way to calculate its quanta. Furthermore, field physics is at least 25 times older and can be traced back all the way to the early Greek...
