Spiral Dynamics in Pattern-Forming Systems: Mean Flow Effects
Mean flow effects are discussed for two different pattern-forming systems: RayleighBénard convection and Faraday instability in viscous fluid. In both systems spirals are observed in certain parameter regions. In the Rayleigh-Bénard convection, the spiral core instability and subsequent generation of upand downflow hexagons are shown to occur due to the mean flow generated by the curved rolls n...
متن کاملSpiral dynamics in pattern - forming systems : mean - ow e ects
Meanow e ects are discussed for two di erent pattern-forming systems: Rayleigh–B enard convection and Faraday instability in viscous uid. In both systems spirals are observed in certain parameter regions. In the Rayleigh–B enard convection, the spiral-core instability is shown to occur due to the mean ow generated by the curved rolls near the core. In the Faraday instability, the mean ow which ...
متن کاملDynamic effects induced by renormalization in anisotropic pattern forming systems.
The dynamics of patterns in large two-dimensional domains remains a challenge in nonequilibrium phenomena. Often it is addressed through mild extensions of one-dimensional equations. We show that full two-dimensional generalizations of the latter can lead to unexpected dynamic behavior. As an example we consider the anisotropic Kuramoto-Sivashinsky equation, which is a generic model of anisotro...
متن کاملMean flow and spiral defect chaos in Rayleigh-Bénard convection.
We describe a numerical procedure to construct a modified velocity field that does not have any mean flow. Using this procedure, we present two results. First, we show that, in the absence of the mean flow, spiral defect chaos collapses to a stationary pattern comprising textures of stripes with angular bends. The quenched patterns are characterized by mean wave numbers that approach those uniq...
متن کاملLocalized states in bistable pattern-forming systems.
We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously generated by the system itself. We show that the phenomenon is generic and requires only the coexistence of two spatially periodic states. At the onset of the spatial bifurc...
