Sketches of the reactors used in the experiments: disk-shaped OSFR (a) and annular OSFR (b), where w is the thickness of the disk and width of the annulus.
Experimental nonequilibrium phase diagram in the ( , ) plane. Symbols attributed to states of the gel: ▼ stable M state; ▲ stable F state; ● oscillatory M state. The lines indicate the limit of the spatial states.
Stationary F (A) and M (B) states observed in the annular OSFR. The upper part of the gel strip is in contact with the CSTR contents (black), the bottom is an impermeable wall (light gray). In between the gray scale changes from medium gray to white correspond to the pH color indicator chances in the gel, from the alkaline to the acid form.
Front interaction and oscillations observed in the annular OSFR at and . The left part of the annular gel is masked, no direct contact with the CSTR. The location of the mask is indicated by a white stripe (a). The white rectangle indicates the area used in the spatio-temporal representation (b), where the sampling time is .
