Autocatalytic systems in a differential-°ow reactor may undergo a differential-fow-induced chemical instability towards a convectively unstable regime, in which noise-sustained structures may appear. This is the case of a system with Gray{Scott kinet-ics in a packed-bed reactor, as reported in [Phys. Rev. E 67, 056207 (2003)]. In this work, two identical copies of such a system are coupled in master{slave configuration and submitted to independent spatiotemporal Gaussian white noise sources. Numerical simulation of 2D reactors with uniform and Poiseuille fows reveals that the slave system replicates to a very high degree of precision the convective patterns arising in the master one due to the presence of noise. The quality of this synchronization is assessed through several measures. A convective instability in the synchronizationmanifold is theoretically predicted and numerically confirmed.
