On mixed convection modes in a vertical layer with unsteadily deformable boundaries
In this paper, effects of three-dimensional periodic bending of boundaries on a flow in a vertical layer have been investigated in the case of mixed convection. Assuming bending amplitude of oscillations of layer walls, fluid flow velocity and phase velocity of running waves at boundaries to be small, a method of small perturbations has been used. At Grashof numbers close to critical, four different modes of flow have been investigated, and the stability regions and character of transition between them have been determined. The analysis has important applications.
