Abstract

Convective stability of mechanical equilibrium and dynamical processes of finite disturbance evolution in the system of two flat horizontal fluid layers is investigated. Peculiarity of the dynamic behaviour of such systems reveals in the fact that the process of the development of disturbances is dominated by hydrodynamic and heat interaction at the interface. These interactions lead to qualitatively new mechanisms of disturbance evolution which effectively influence both the process of the stability loss and the regularities of the development and interaction of finite disturbances.
