Period Stabilization in the Busse - Heikes Model of the Küppers - Lortz Instability 1
نویسندگان
چکیده
The Busse-Heikes dynamical model is described in terms of relaxational and nonre-laxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes leads to vertex formation. The competition of front motion around the vertices and the Küppers-Lortz instability in determining an alternating period is discussed.

متن کاملHexagonal Patterns in a Model for Rotating convection
We study a model equation that mimics convection under rotation in a fluid with temperaturedependent properties (non-Boussinesq (NB)), high Prandtl number and idealized boundary conditions. It is based on a model equation proposed by Segel [1965] by adding rotation terms that lead to a Kiippers-Lortz instability [Kuppers & Lortz, 1969] and can develop into oscillating hexagons. We perform a wea...
متن کاملChaotic advection and the emergence of tori in the Küppers-Lortz state.
Motivated by the roll-switching behavior observed in rotating Rayleigh-Benard convection, we define a Küppers-Lortz (K-L) state as a volume-preserving flow with periodic roll switching. For an individual roll state, the Lagrangian particle trajectories are periodic. In a system with roll-switching, the particles can exhibit three-dimensional, chaotic motion. We study a simple phenomenological m...
متن کاملGeneration of Mean Flows in a Rotating Convection Layer
The instability of convection rolls in a fluid layer heatet from below is studied in the case where the layer rotates about an axis slightly inclined with respect to the vertical. The inclination destroys the horizontal isotropy of the layer, but the instability of rolls found by Küppers and Lortz [1] is little affected as long as the angle of inclination is small. A new effect is the generatio...
متن کاملPattern Formation in Rayleigh-bénard Convection in a Rapidly Rotating Cylinder
Pattern formation in a rotating Rayleigh-Bénard convection configuration is investigated for moderate and rapid rotation in moderate aspect-ratio cavities. While the existence of Küppers-Lortz rolls is predicted by theory at the onset of convection (Küppers and Lortz, 1969; Busse and Clever, 1979), square patterns have been observed in physical (Bajaj et al., 1998) and numerical experiments (Sá...
