Chaos and Hyperchaos in a Model of the Belousov-Zhabotinsky Reaction in a Batch Reactor

A simplification down to twenty six reaction steps of twenty species from the Gyorgyi, Turanyi and Field model (GTF) with eighty steps and twenty six species of the Belousosv-Zhabotinsky reaction is shown to be enough to account for recently available experimental results obtained by Rouff in a batch reactor. The bromate concentration was used as the control parameter for the system. Upon variation of this parameter we see the evolution of the system from an excitable steady-state to a limit cycle, then to a subsequent hyperchaotic regime through crisis, and back to a steadystate.
