- 論文の詳細を見る
The Rayleigh-Benard convection in a binary fluid mixture is studied using a model system of coupled-mode equations for several chosen sets of the external parameters. The field variables are assumed to be two-dimensional and periodic in the horizontal direction. The velocity, the temperature and the concentration variables obey the rigid, Isothermal and impermeable boundary conditions on the horizontal surfaces respectively. The system with increase of the Rayleigh number develops periodic, quasi-periodic and non-periodic travelling waves of the convection rolls one after another. In particular, the non-periodic waves change the direction of propagation with irregular time intervals.
