“…The reactor, developed in collaboration with Ouyang et al [8], is a circular Couette system: the reaction occurs in an annular region formed by two concentric cylinders, the inner of which is rotating while the outer one is stationary [6,8,9] #1. Reagents are fed and removed at each end of the annulus; the flow rates are carefully adjusted so that there is no net mass flux in the axial direction.…”

We have developed a novel spatially extended chemical reactor that can be maintained indefinitely in a well-defined nonequilibrium state. The system is effectively one-dimensional, Reagents of the Belousov-Zhabotinsky reaction are fed at both ends, the oxidizer at one end and the reducer at the other end, but there is no net mass flux in the reactor. The system is designed so that the effective diffusion coefficient, which is the same for all species (typically 0.1 cm2/s), can be varied; spatiotemporal patterns were studied for several values of the diffusion coefficient. The following sequence of well-defined dynamical regimes was observed as the gradient in oxidizer concentration was increased with other control parameters held fixed: steady, periodic, quasiperiodic, frequency-locked, period-doubled, and chaotic. The transitions to different regimes occurred with no observable hysteresis. This is the first observation of a sequence of spatiotemporal regimes in a laboratory reaction-diffusion system. These observations are described qualitatively by a simple reaction-diffusion model with only two species.

The first experimental observation of a bifurcation sequence of patterns in a reaction-diffusion system is reported. The experiment on a one-dimensional system, maintained away from equilibrium, reveals steady, periodic, quasiperiodic, frequency-locked, period-doubled, and chaotic spatiotemporal states. Results from a model reaction-diffusion system agree qualitatively with the experiment and provide insight into the physical mechanism that drives the observed behavior.
