Transition from spirals to defect-mediated turbulence driven by a doppler instability.

چکیده
A transition from rotating chemical spirals to turbulence is observed in experiments on the Belousov-Zhabotinsky reaction. The transition occurs when the waves near the spiral tip spontaneously break, generating defects. Measurements reveal that this defect-mediated turbulence is caused by the Doppler effect on the traveling waves. The observations are in good accord with numerical simulations and theory.

Transition from spiral waves to defect-mediated turbulence induced by gradient effects in a reaction-diffusion system.
The transition from spiral waves to defect-mediated turbulence was studied in a spatial open reactor using Belousov-Zhabotinsky reaction. The experimental results show a new mechanism of the transition from spirals to spatiotemporal chaos, in which the gradient effects in the three-dimensional system are essential. The transition scenario consists of two stages: first, the effects of gradients ...
متن کاملThe effect of ISM turbulence on the gravitational instability of galactic discs
We investigate the gravitational instability of galactic discs, treating stars and cold interstellar gas as two distinct components, and taking into account the phenomenology of turbulence in the interstellar medium (ISM), i.e. the Larson-type scaling relations observed in the molecular and atomic gas. Besides deriving general properties of such systems, we analyse a large sample of galaxies fr...
متن کاملTargets, ripples and spirals in a precipitation system with anomalous dispersion.
We present a novel reaction-diffusion system that exhibits three-dimensional superdiffusive traveling waves without utilizing any external forces. These waves include single circular targets, spirals, and ripples as well as phase-like waves. The system is based on the interplay of the precipitation reaction of mercuric iodide in a gel medium, its polymorphic transformation to a different crysta...
متن کاملSupercritical transition to turbulence in an inertially-driven von Karman closed flow
We study the transition from laminar flow to fully developed turbulence for an inertially-driven von Kármán flow between two counter-rotating large impellers fitted with curved blades over a wide range of Reynolds number (10 − 10). The transition is driven by the destabilisation of the azimuthal shear-layer, i.e., Kelvin–Helmholtz instability which exhibits travelling/drifting waves, modulated ...
متن کاملThe role of turbulence–flow interactions in L- to H-mode transition dynamics: recent progress
Recent experimental and simulation work has substantially advanced the understanding of L-mode plasma edge turbulence and plasma flows and their mutual interaction across the L–H transition. Flow acceleration and E × B shear flow amplification via the turbulent Reynolds stress have been directly observed in multiple devices, using multi-tip probe arrays, Doppler backscattering, beam emission sp...
