Travelling waves in an ionic quadratic autocatalytic chemical system
The influence of a constant electric field on the travelling waves that are initiated in an ionic autocatalytic reaction-diffusion system with quadratic rate law is considered. The necessary conditions for the existence of minimum speed travelling waves are established and examples of such waves have been generated using numerical simulation. The behaviour of the system when the necessary conditions are not satisfied is also examined. This behaviour involves electrophoretic separation and reaction termination, each of which is discussed using examples obtained from numerical simulation. (C) 1999 Elsevier Science Ltd.
