【 摘 要 】

The present paper is devoted to the investigation of the onset and nonlinear regimes of the vibrational convection of ternary mixtures in rectangular cavities with rigid boundaries in zero gravity conditions. We consider translational linearly polarized vibrations of finite amplitude and frequency. The axis of vibrations is perpendicular to the temperature gradient. The problem is solved by finite difference method in the framework of 2D unsteady approach. Numerical data on the time evolution of instantaneous and average fields and characteristics of convective flows and concentration fields are obtained for different vibration intensities and aspect ratios.
