Simulation of oscillatory chemical reactions with chaotic behavior

The present paper deals with the simulation of oscillatory chemical reactions with chaotic behavior based on the classical model of O. Rössler. The attractors of the system and Lyapunov exponents are numerically calculated when one of the parameters changes. The transition scenario from order to chaos is investigated. System solution behavior in chaotic mode is described qualitatively. Autocorrelation functions, invariant measures of some quantities, and one-dimensional maps of some interesting attractors are constructed using the Poincare section. A qualitative comparison of bifurcation diagrams by the original system and the resulting one-dimensional map is performed.
