Poincare recurrences from the perspective of transient chaos
Eduardo G. Altmann, Tamas Tel
We obtain a description of the Poincaré recurrences of chaotic systems in terms of the ergodic theory of transient chaos. It is based on the equivalence between the recurrence time…
Signatures of fractal clustering of aerosols advected under gravity
Rafael Dias Vilela, Tamás Tél, Alessandro P. S. de Moura +1
Aerosols under chaotic advection often approach a strange attractor. They move chaotically on this fractal set but, in the presence of gravity, they have a net vertical motion down…
Oscillation and levitation of balls in continuously stratified fluids
I. Biro, B. Gyure, I. M. Janosi +2
The free motion of balls is investigated experimentally in continously stratified fluid in a finite container. The oscillation frequency is found to be very close to the local Brun…
Vortex flow generated by a magnetic stirrer
G. Halasz, B. Gyure, I. M. Janosi +2
We investigate the flow generated by a magnetic stirrer in cylindrical containers by optical observations, PIV measurements and particle and dye tracking methods. The tangential fl…
Competing Populations in Flows with Chaotic Mixing
I. Scheuring, G. Karolyi, Z. Toroczkai +2
We investigate the effects of spatial heterogeneity on the coexistence of competing species in the case when the heterogeneity is dynamically generated by environmental flows with…
