Abstract:
The stability of an interface of two binary mixtures under any perturbations is investigated. The dependence of the complex decrement on the wave number is deduced by means of a numerical method of orthogonalization. We show that the area of instability increases for not deformable interfaces at increase of the Marangoni number, too. The areas of stability of a system with growth thermal diffusion effects on an interface are determined.
Keywords:surface tension, Marangoni the number, stability, thermal diffusion.
