Modulation Induced Nonlinear Phase Transitions of Small Amplitude Oscillation in CSTR-BZ Reaction
Abstract:
Nonlinear phase transitions are observed both from experiment and simulations in the modulated CSTR-BZ reaction system. The small amplitude oscillation of potential at low flow region is perturbed by periodic or noise (random) signal on the flow. Phase transition may occur under certain conditions (perturbation frequency and perturbation amplitude).The 4-variables Montanator model is used in the modeling calculations, and our experiments are in qualitative agreement with the model calculations.
