Abstract

We have explored the growth of patterns in chlorine dioxide-iodine-malonic acid reaction-diffusion system when the injection rate of the activator and inhibitor is varied over a range. The transition from spot to stripe and their mixture and finally the target wave which appears at the Hopf bifurcation boundary are observed. Our numerical simulations have been corroborated by theoretical analysis of amplitude equation for targets.
