Stability of Flows
In the present chapter, the stability of convective flows in multilayer systems is considered. First, we will discuss general mechanisms of instabilities for flows generated by a surface-tension gradient applied along the surface (Section 5.1). Then, we present a linear analysis of thermocapillary flows in two-layer systems subject to an inclined temperature gradient (Section 5.2). Results of the investigation of buoyancy-thermocapillary convection in two-layer and three-layer systems are given in Sections 5.3 and 5.4, respectively. Section 5.5 contains an analysis of deformational instabilities of thermocapillary flows in three-layer systems.
