Abstract (in Japanese) (See Japanese page) 
(in English) In this presentation, we would like to reviews recent progress in our convective motion in binary fluid mixtures with through-flow together with one of our published paper ( Prog. Theor. Phys. 106.1115 (2001).) by using the SIMPLE algorithm simulation technique. The simulations were performed in a channel of aspect ratio Г=L/d = 12, for an ethanol-water mixture at room temperature with Prandtl number σ=10, Lewis number L=0.01. The separation ratio ψ=-0.1 was chosen as a representative case for moderately negative Soret coupling. In most of situations, a weak through flow with Re=0.08 was applied. The significant phenomena of this system revealed in our simulations are the repeated evolution and steady coexistence of linear and nonlinear TWs. In a linear growth process, the counter-propagating traveling waves for Re=0 with equal growth rates and frequencies were replaced by the boundary conditions are responsible for this behavior.
