Abstract
Experiments with catalytic CO oxidation on Pt(110) show that chemical turbulence in this system can be suppressed by application of appropriate global delayed feedbacks. Different spatiotemporal patterns, seen near a transition from turbulence to uniform oscillations, are investigated. Using a method based on the Hilbert transform, spatial distributions of local phase and amplitude in such patterns are reconstructed from the experimental data. The observed phenomena are reproduced in simulations using a theoretical model of the reaction.
