Abstract

Past experiments on the formation of chemical spatial structures 1-4 (mainly chemical waves) have been conducted in closed, batch systems such as Petri dishes5-15, and not in open chemostats such as those usually employed in the study of temporal structures. As a consequence, the observed spatial patterns change uncontrollably and ultimately decay as the mixture evolves towards thermody-namic equilibrium. We have overcome this problem in a novel type of open reactor: the reaction occurs in an annular inert gel that is fed at the inner and outer rims. The reaction that we have studied is the Belousov-Zhabotinskii (BZ) reaction, which has become the paradigm for studies of spatial and temporal structures in nonlinear systems. In the ring reactor we observe sustained travelling azimuthal waves for a wide range of conditions.
