Abstract

Hydrodynamical effects due to Marangoni instability in the Big Wave, which is the wave observed in a quasi 2-dimensional shallow layer of unstirred excitable Belousov-Zhabotinsky (BZ) reaction solution, were investigated experimentally. We found that the layer depth of BZ solution strongly influences the propagating velocity and the shape of the wave. The critical depth d(c) of BZ solution was found to be d(c) approximate to 1.5 mm. The qualitative feature of the propagation of the wave changed at d(c). We also determined the difference between the location of the maximum deformation of the surface and that of a wave front such as the color front.
