Resumen:
The differential-flow-induced chemical instability is investigated in the context of two coupled reactors withcubic autocatalytic kinetics (theGray-Scott model). Previous results formaster-slave arrangement [Iz´us, Deza, andS´anchez, J. Chem. Phys. 132, 234112 (2010)] are extended in this study to include bidirectional coupling betweenreactions. Numerical simulations in the convectively unstable regime show that synchronized noise-sustainedstructures are developed in both reactors due to the selective amplification of noise. A theoretical analysis showsthat the nature of the synchronization and the stability of the synchronized manifold are related with the propertiesof the critical modes
