The cavity can be divided into two typical zones: the Rayleigh_Benard-like convection zone governed by the centrifugal buoyancy force occupying the upper cavity, and the forced convection zone governed by the inertial-force down under. These two zones interact with each other via the exchange of mass, momentum and energy.

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.
