Abstract
The effect of a limited stirring phase on the general behavior of the periodic color change in the Belousov Zhabotinsky was investigated systematically. The effects of stirring on the BZ reaction has other consequences too apart from the pure homogenization of the system. We have investigated the system under different conditions (changing dimensions and volume of the beaker, different stirring rates and times). We found that the stirring can result in the disappearance of an aperiodic phase which is present in the non-stirred case. We suppose that the stirring time plays the role of a ‘bifurcation parameter’.KeywordsBelousov Zhabotinsky reactionStirringRotational flow
