Author(s): Thomas D. Nevins and Douglas H. KelleyWe investigate growth of the excitable Belousov-Zhabotinsky reaction in chaotic, time-varying flows. In slow flows, reacted regions tend to lie near vortex edges, whereas fast flows restrict reacted regions to vortex cores. We show that reacted regions travel toward vortex centers faster as flow spe…[Phys. Rev. Lett. 117, 164502] Published Fri Oct 14, 2016
