Oscillation Phase Dynamics in the Belousov - Zhabotinsky Reaction
نویسندگان
چکیده
The phase jumps dynamics in a photosensitive BelousovZhabotinsky reaction has been studied. It was found that an initially inhomogeneous phase distribution evolved to a homogeneous one, so that the phase at phase-lag points rises to the value at phase-lead points. A steep phase distribution was shown to become smoother in the course of time, inducing a dephasing wave which restores the system to a uniform phase. Applications of photosensitive chemical reactions to image processing (image storage, inversing, contouring) are discussed. Acknowledgments. Many thanks to Drs. Vadim N. Biktashev and Mikhail R. Stepanov for helpful discussions of the subject; special acknowledgments to Professor Arthur T. Winfree who read the manuscript carefully and helped in its structure improvement.

Dynamics of the Oscillation Phase Distribution in the BZ Reaction
Oscillation phase dynamics in the homogeneous autooscillating Belousov-Zhabotinsky (BZ) reaction has been studied by computer simulations. The wave dynamics in autooscillating media is qualitatively di erent from those in excitable media for su ciently long waves. We propose a classi cation of chemical waves which is based on the analysis of shape of the dispersion curve. This delimits conventi...
متن کاملIdentification of a temperature Dependent FitzHugh-Nagumo Model for the Belousov-Zhabotinskii reaction
This paper describes the identification of a temperature dependent FitzHugh–Nagumo model directly from experimental observations with controlled inputs. By studying the steady states and the trajectory of the phase of the variables, the stability of the model is analyzed and a rule to generate oscillation waves is proposed. The dependence of the oscillation frequency and propagation speed on th...
متن کاملOn the Phase Dynamics in the BZ Reaction
We have studied the phase dynamics in an oscillatory chemical system (Belousov-Zhabotinsky reaction). The phase distribution and isophase lines in the 2D phase space were reconstructed. The dynamics proved to be well described in terms of the Burgers equation. The phase dependence of the coefficients of the equation was taken into account to estimate the region of the applicability of the Burge...
متن کاملCanard phenomenon and localization of oscillations in the Belousov–Zhabotinsky reaction with global feedback
The occurrence of spatial domains of large amplitude oscillation on a background of small amplitude oscillation in a reaction–diffusion system is called localization. We study, analytically and numerically, the mechanism of localization in a model of the Belousov–Zhabotinsky reaction subject to global feedback. This behavior is found to arise from the canard phenomenon, in which a limit cycle s...
متن کاملOn the Origin of Chaos in the Belousov-Zhabotinsky Reaction in Closed and Unstirred Reactors
We investigate the origin of deterministic chaos in the Belousov–Zhabotinsky (BZ) reaction carried out in closed and unstirred reactors (CURs). In detail, we develop a model on the idea that hydrodynamic instabilities play a driving role in the transition to chaotic dynamics. A set of partial differential equations were derived by coupling the two variable Oregonator–diffusion system to the Nav...
