Stationary flow- and diffusion-distributed structures (FDS) patterns appear in a reaction-diffusion-advection system when a constant forcing is applied at the inlet of the reactor. We show that if the forcing is subject to noise, the FDS can be destroyed via the noise-induced Hopf instability. However, the FDS patterns are restored if the flow rate is sufficiently high. We demonstrate that the critical flow rate which is required for the stabilization of FDS has a power-law dependence on the noise amplitude.

The flow- and diffusion-distributed structures (FDS) and the differential-flow instability (DIFI) are mechanisms that give rise to static and traveling waves in reactive flows with general, species-dependent transport terms. Here we consider a general framework which supports the simultaneous existence of FDS and DIFI patterns. We study the necessary conditions for each instability in general and compare them in order to derive their connection.
