title: Turbulent decomposition of chemical waves by spontaneously induced hydrodynamic oscillation.
abstract: The dynamic evolution of a chemical reaction-diffusion pattern and its interaction with hydrodynamic flow is investigated by two-dimensional velocimetry and spectrophotometry based on microscope video imaging techniques. Oscillatory deformation and turbulent decomposition of chemical wave fronts are observed which are induced by a pronounced oscillatory flow excited spontaneously in a Belousov-Zhabotinsky solution layer with a free surface.
