Experimental study of spiral waves in the cerium-catalyzed Belousov-Zhabotinskii reaction

Systematic measurements of spiral wave characteristics (rotation period, normal velocity, wavelength, and wave form) in the cerium-catalyzed BZ reaction were carried out over a wide range of reagent concentrations. These data provide a stringent test for theoretical models of the reaction. Numerical calculations of spiral wave solutions to modified Oregonator equations are in satisfactory agreement with the experimental results
