Spiral waves over metal catalysts

Abstract
Selection formulas for the wavelength and frequency of uniformly rotating spiral waves are derived for the general class of three-variable models of single-diffusive excitable-oscillatory media and applied to make quantitative predictions that could be experimentally tested for the model proposed by Sales, Turner, and Maple [Surf. Sci. 114, 381 (1982)] to describe the oscillatory oxidation of CO over polycrystalline metal catalysts.
