Abstract: | A plane steady-state two-layer fluid flow under the coupled action of the buoyancy and Marangoni forces is considered. The
system is oriented at an arbitrary angle with respect to the gravity force. Exact solutions generalizing the Ostroumov-Birikh
solution are obtained and their stability is studied in the framework of a linear theory. On the basis of numerical calculations,
the influence of the inclination angle, the thickness of the layers, and the wall heating conditions on the instability mechanisms
is investigated. |
