SPATIOTEMPORAL PATTERNS IN SIMPLE REACTION CELL ARRAYS WITH TIME-DELAY

The effects of the intensity of coupling and the time delay on the pro perties of circulating spatiotemporal firing patterns in several simpl e cell arrays have been studied for the Belousov-Zhabotinskii (BZ) and chlorine dioxide-iodide reaction kinetics models. Single firing and f inite cascade of firings have been found for both systems, but permane nt firing has been observed only in the Oregonator model of the BZ rea ction. The existence of regimes with permanent firing have been explai ned on the basis of the difference in the course of concentration traj ectories of the studied systems.
