Abstract
Advection-reaction-diffusion (ARD) waves in the Belousov-Zhabotinsky reaction in steady Taylor-Couette vortices have been visualized using magnetic-resonance imaging and simulated using an adapted Oregonator model. We show how propagating wave behavior depends on the ratio of advective, chemical and diffusive time scales. In simulations, inward propagating spiral flamelets are observed at high Damkoumlhler number (Da). At low Da, the reaction distributes itself over several vortices and then propagates inwards as contracting ring pulses-also observed experimentally.
