The dynamic behavior of chemical patterns induced by the coupling of chemical waves and hydrodynamic flows in the Belousov-Zhabotinskii reaction was investigated by 2D spectrophotometry and 2D velocimetry. Periodically varying deformations of chemical-wave profiles were observed in a reactive layer with a liquid/gas interface. They are due to an oscillatory hydrodynamic flow detected close to the layer surface.
