Self-Organized Traveling Chemo-Hydrodynamic Fingers Triggered by a Chemical Oscillator D. M. Escala M. A. Budroni J. Carballido-Landeira A. De Wit A. P.

In regular oscillatory conditions, localized periodic changes in the concentration of intermediate species induce pulsatile density gradients, which, in turn, generate traveling convective fingers breaking the transverse symmetry. These patterns are the self-organized result of a genuine coupling between chemical and hydrodynamic modes. 2015-12-17 00:29:02 contact zone oscillatory conditions pattern pulsatile density gradients chemical oscillations gravity field chemical reaction convective fingers hydrodynamic modes
