摘要：

This article deals with two-dimensional Soret-driven convection in a porous cavity with perfectly conducting boundaries heated from below. It is shown that thermodiffusion effect destroys degeneracy existing in the case of single-component fluid. The scenario of the convection onset is discussed. The boundaries of the diffusive state instability to the small-amplitude and finite-amplitude monotonous and oscillatory perturbations are determined. (C) 2011 Academie des sciences.
