We report an experimental study of the onset of convection in ethanol-water mixtures con ned in a circular cell of radial aspect ratio 11.6. The initial bifurcation was to radial traveling waves; however, the linear state typically gave way to a nonlinear one in which convection alternately focused along one cell diameter and then another roughly perpendicular to the rst. After a number of cycles, this state frequently collapsed to a localized pulse of traveling-wave convection very similar to… CONTINUE READING
