Název v původním jazyce

Complex oscillatory dynamics in a pH oscillator

Popis výsledku v původním jazyce

The reaction of hydrogen peroxide, thiosulfate and sulphuric acid catalyzed by cupric ions (HPTCu reaction1) displays a rich nonlinear behaviour marked by multiple steady states, excitability and oscillations in a continuous-flow stirred tank reactor (CSTR) operated under isothermal conditions. The HPTCu reaction is a so called pH oscillator because the oscillations observed during experiments exhibit large changes in pH value, typically in the range of pH between 4 and 6. The reaction displays not onlysimple oscillations but also complex oscillations. It has been observed in earlier work that a large peak may be followed by a series of small-amplitudes oscillations and that the length of the phase of small oscillations may vary in a regular or irregular fashion. However, these measurements have not been made with the aim of systematic study of the transitions between various regular and irregular dynamical regimes. The main purpose was to establish that the system is oscillatory. At
