Abstract

The oscillatory regime of convective motion was studied experimentally. The onset of this mode is associated with the diffusion of surfactants in a system of liquids with a vertical interface blocking the horizontal channel. The specific feature of the problem under consideration is the equality of initial densities of all liquids, both the basic and diffusing ones. The data obtained during the experiment allowed us to describe the structure of flows and concentration fields and to analyze the dynamics of the oscillatory mode of convection. The experimental data were compared with the results of the numerical calculation.
