Regularities in Complex Asymptotic Oscillations in the Belousov-Zhabotinsky Reaction at Various Residence Times and Inflow Malonic Acid Concentration

摘要

Simple and complex oscillations have been observed in an asymptotic regime of the Belousov-Zhabotinsky (BZ) system of bromate-malonic acid-ferroin in a continuously stirred tank reactor (CSTR).Changes of the residence time and the influx concentration of malonic acid induce the appearance of regularities in complex patterns which resemble the period adding bifurcation.All experimental results can be reproduced by a simple model suggested earlier for qualitative description of asymptotic and transient oscillations observed in the BZ system.
