Convection in binary mixtures: The role of the concentration field
Structure and dynamics of different roll states appearing close to onset of convection in binary mixtures and the influence of the concentration field on the properties of these states are elucidated. Numerical solutions of the hydrodynamic field equations in a vertical cross section perpendicular to the roll axes are reviewed for room temperature ethanol- water parameters. Extended states of stationary overturning convection and of traveling wave convective rolls are investigated as well as spatially confined states of localized travelling wave rolls. The field structure and symmetries of these states are discussed.
