Investigation of dynamic behavior of the Bray-Liebhafsky reaction in the CSTR. Properties of the system examined by pulsed perturbations with I ^-

Abstract

In order to investigate the properties of the dynamic states in the Bray-Liebhafsky (BL) reaction, pulsed perturbations with iodide are applied. In particular, the excitability thresholds of several stable stationary states corresponding to the same non-equilibrium stationary state branch, as well as the excitability thresholds and phase response behavior of one oscillatory state, are investigated and characterized quantitatively. In the oscillatory state, the phase response behavior corresponding to perturbations of different strengths is determined, and characterized by phase response curves (PRC and PTC). Finally, all values obtained experimentally are also calculated, using one variant of a model of the Bray-Liebhafsky reaction.
