A. Kudrolli et Jp. Gollub, LOCALIZED SPATIOTEMPORAL CHAOS IN SURFACE-WAVES, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 54(2), 1996, pp. 1052-1055
A route to spatiotemporal chaos (STC) is identified in parametrically
forced surface waves in which strongly disordered fluctuating domains
coexist with textured stripes. The chaotic domains of this mixed state
nucleate via instability at the most strongly curved regions of the s
tripe pattern. The area covered by the STC grows with the imposed acce
leration, and fills all regions where the local curvature exceeds an E
-dependent critical curvature. The striped domains within the mixed st
ate are also distorted by a secondary oscillatory instability at moder
ate viscosity.
