Localized structures (LSs) in dissipative media appear in various fields of natural science
such as biology, chemistry, plant ecology, optics and laser physics. The proposal for this …

We numerically explore the propagation of reacting fronts in a shallow and horizontal layer
of fluid. We focus on fronts that couple with the fluid due to density differences between the …

We analyze experimentally chemical wave propagation in the disordered flow field of a
porous medium. The reaction fronts travel at a constant velocity that drastically depends on …

Recent theoretical and experimental work has demonstrated the existence of one-sided,
invariant barriers to the propagation of reaction-diffusion fronts in quasi-two-dimensional …

Front propagation in one-and two-dimensional spatially modulated media is studied both
experimentally and theoretically. The pinning-depinning phenomenon, long ago predicted …

We present experiments on reactive front propagation in a two-dimensional (2D) vortex
chain flow (both time-independent and time-periodic) and a 2D spatially disordered (time …

We present experimental studies of reaction front propagation in a single vortex flow with an
imposed external wind. The fronts are produced by the excitable, ferroin-catalyzed Belousov …

The dynamics of fronts, such as chemical reaction fronts, propagating in two-dimensional
fluid flows can be remarkably rich and varied. For time-invariant flows, the front dynamics …

We present experiments on the behavior of reaction fronts in extended, vortex-dominated
flows in the presence of an imposed wind. We use the ferroin-catalyzed, excitable Belousov …

Using lattice Boltzmann simulations, we analyze the different regimes of propagation of an
autocatalytic reaction front in heterogenous porous media. The heterogeneities of the …
