Turing structures and turbulence in a chemical reaction-diffusion system
Jensen O., Pannbacker VO., Mosekilde E., Dewel G., Borckmans P.
Turing structures and turbulence are analyzed within the framework of a model for the chlorine dioxide-iodine-malonic acid reaction. This reaction has recently provided the first experimental results on the formation of stationary chemical patterns under laboratory conditions. The model is distinguished from previously studied simple reaction-diffusion models by showing a strongly subcritical transition to stripes. This makes it possible for a great variety of localized structures to emerge and be stable. The dynamics of phase singularities and the formation and breakdown of chemical spirals are investigated. © 1995 Nicholas Copernicus University Press.
