Abstract
The Dynamics of the Belousov-Zhabotinsky (BZ) coupled map lattice (CML) was studied as a model of spatiotemporal pattern. The systematical change of coupling strength and bifurcation parameter led to the shifts in the patterns of the BZ CML. The phase diagram of the BZ CML was different from that of the logistic CML. The phases, such as fully developed turbulence, pattern competition intermittency and pattern selection observed in the logistic CML, appeared in the BZ CML. However, the dynamics of the BZ CML were more sensitive to the coupling strength than those of the logistic CML. In addition, the periodic oscillation phase was observed as small a number of patterns without the domain of chaotic motion. Furthermore, we discussed the difference between the BZ and the logistic CML on the basis of intermittency of chaos.
