Diffusive feed of reactants and Hopf bifurcations in an oscillatory reaction-diffusion model

摘要

We study an oscillatory chemical model (the “Brusselator”) with the aim of analyzing the effect of a controlled diffusive feed of reactants in the appearance of chemical oscillations. The reflectivities of the boundary, which adjust the external fluxes, act as control parameters capable to alter the attractive basin of the thermodynamic branch, leading to oscillatory behavior. © 1999 American Institute of Physics.
