Oregonator
Encyclopedia
The Oregonator is a theoretical model for a type of autocatalytic reaction
.
The Oregonator (Orygunator) is the simplest realistic model of the chemical dynamics of the oscillatory Belousov-Zhabotinsky reaction
.
It was created by Richard M. Noyes
at the University of Oregon
. It is a portmanteau of Oregon
and oscillator.
Earlier, the Brusselator
model was proposed by Ilya Prigogine
and his collaborators at the Free University of Brussels
as a portmanteau of Brussels
and oscillator.

Autocatalytic reaction
Autocatalytic reactions are chemical reactions in which at least one of the reactants is also a product. The rate equations for autocatalytic reactions are fundamentally nonlinear. This nonlinearity can lead to the spontaneous generation of order. A dramatic example of this order is that which is...

Belousov-Zhabotinsky reaction
A Belousov–Zhabotinsky reaction, or BZ reaction, is one of a class of reactions that serve as a classical example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator. The only common element in these oscillating systems is the inclusion of bromine...
