| Résumé : | It is known from a long time that the decomposition of hydrogen peroxide catalysed by hydrogen and iodate ions, the Bray-Liebhafsky reaction, can give oscillations in a batch reactor. Recently, mixed-mode oscillations and chaos were also observed in a CSTR. The model we had proposed to explain the kinetics in a batch reactor can as well simulate these new complex behaviours. Time series give only a limited view of the features of the calculated behaviours and more information is obtained studying the properties of the state space. We use projections of the trajectories, calculation of the correlation dimension of the attractor, Poincaré sections and return maps. As the state space of the model is six-dimensional, we try to answer two questions: Do the projections into a 3D subspace give correct pictures of the real trajectories? Have we reasons to prefer a special subspace? |
