✦ Synopsis

The stirring-induced bifurcation at low stirring rate S o = 23 rpm of the reaction volume has been observed for the chaotic regime in the Belousov-Zhabotinsky oscillating chemical reaction (malonic acid-bromate-cerium(III)-sulfuric acid) in a continuously stirred tank reactor in premixing mode. This bifurcation is characterized by a stepwise growth of the macroscopic spatial concentration gradients that is shown by the use of the time dependencies of the potential difference between two platinum electrodes.
