Experimental observations of periodic and chaotic regimes in a forced chemical oscillator

Abstract

Abstract Experiments showing periodic and chaotic behavior in a Belousov-Zhabotinski (BZ) reaction mixture in a stirred flow reactor with periodic addition of bromide ions are presented. An alternating sequence of periodic and aperiodic regimes as a function of the period of Br - pulses is observed in experiments. This behavior is well described by a simple model based on the results of single-pulse experiments.
