Phenomenological model of chaotic mode competition in surface waves

  • Published:
Il Nuovo Cimento D

Summary

We present a four-variable model (two coupled parametrically forced oscillators) that describes many of the phenomena seen in an experiment on surface waves in which the competition between spatial patterns produces chaotic behaviour. The model reproduces the route to chaos, the dimension of the attractor, the Kolmogorov entropy and (approximately) the phase diagram.

Riassunto

Si presenta un modello a quattro variabili (due oscillatori accoppiati forzati parametricamente) che descrive molti dei fenomeni visti in un esperimento sulle onde di superficie nel quale la competizione fra le configurazioni spaziali produce un comportamento caotico. Il modello riproduce la via al caos, la dimensione dell'attrattore, l'entropia di Kolmogorov e (approssimativamente) il diagramma di fase.
