Spiral pattern in chlorite-iodide-malonic acid reaction: a theoretical and numerical study.

The development of spiral pattern in a model representing chlorite-iodide-malonic acid reaction is investigated theoretically and numerically. We have carried out a multiple scale analysis of the model to identify the experimentally admissible parameter range and the appropriate perturbation for shifting Hopf bifurcation boundary towards the oscillating region. Our theoretical analysis is corroborated by numerical simulation.
