OAK-B135 Thermal convection was studied in a horizontal layer of a binary fluid mixture of ethanol and water confined in a variety of cell geometries. In these mixtures, convection takes the form of traveling waves, thus providing a model for studying traveling-wave (TW) phenomena in non-equilibrium systems. A number of questions were addressed, including the evolution of initially chaotic states, the role of TW domains textures and convection-cell geometry in determining patterns, and the competition of TW and hexagonal patterns when non-Boussinesq effects are important
