SPATIAL AND TEMPORAL CONCENTRATION PATTERNS IN COUPLED BELOUSOV-ZHABOTINSKY OSCILLATORS

The coupling of two identical chemical oscillators containing B-Z reag ents and modelled by the Oregonator model is examined. The coupling, u nlike our previous work, is only via the cerium component, while other species are not coupled. Formation of spatial and temporal inhomogene ities is found. Transitions from spatial homogeneous steady state to i nhomogeneous one, and then to spatial homogeneous and inhomogeneous os cillations are examined. Analysis of the system as a function of the c oupling late and the stoichiometric factor leads to a number of region s in which different patterns are observed. The feasibility of experim ental verification of these steady states and oscillations is discusse d.
