Oregonator

The Oregonator is similar to the Brusselator, a model for the description of oscillating chemical reactions. It was proposed in 1972 by Richard J. Field, Endre Körös and Richard M. Noyes of the University of Oregon to describe the Belousov -Zhabotinsky reaction. Received the name of it, based on the Brusselator, as Fields et al. worked at that time at the University of Oregon (the name itself is a word Brusselator intersection of the name of the city of Brussels and oscillator ). But it is also often simply called after the initials of the authors, FKN model.

The model

Oregonator the model consists of five reactions seven chemical species {A, B, P, Q, X, Y, Z }:

The concentrations of species A and B are kept constant, and the products P and Q are constantly removed, thus only three variables need to be considered. Wherein f (V) is another parameter (such as the concentration [A] and [B]).

This results in the rate equations:
