Evidence of fractional transport in point-vortex flow
Xavier Leoncini, Leonid Kuznetsov, George M. Zaslavsky
Advection properties of passive particles in flows generated by point vortices are considered. Transport properties are anomalous with characteristic transport exponent …
Passive Tracer Dynamics in 4 Point-Vortex Flow
A. Laforgia, X. Leoncini, L. Kuznetsov +1
The advection of passive tracers in a system of 4 identical point vortices is studied when the motion of the vortices is chaotic. The phenomenon of vortex-pairing has been observed…
Chaotic Advection near 3-Vortex Collapse
X. Leoncini, L. Kuznetsov, G. M. Zaslavsky
Dynamical and statistical properties of tracer advection are studied in a family of flows produced by three point-vortices of different signs. A collapse of all three vortices to a…
Motion of Three Vortices near Collapse
X. Leoncini, L. Kuznetsov, G. M. Zaslavsky
A system of three point vortices in an unbounded plane has a special family of self-similarly contracting or expanding solutions: during the motion, vortex triangle remains similar…
