Experimental observations have played a crucial role in advancing our understanding of pattern formation in nonequilibrium systems. From the study of convective flows in fluids to the observation of spiral waves in chemical reactions, experiments have provided a wealth of information on the dynamics of nonequilibrium systems.
In a well-mixed chemical reactor, reactions proceed monotonically. However, in the BZ reaction, nonlinear feedback loops (autocatalysis) drive the system into oscillatory behavior. In a spatial medium, this creates and Spiral Waves . These are not static structures but waves of chemical concentration propagating through the medium. pattern formation and dynamics in nonequilibrium systems pdf
