Convection under rotation for Prandtl numbers near 1 : Küppers-Lortz instability

The Küppers-Lortz~KL ! instability in Rayleigh-Be ́nard convection rotated about a vertical axis was studied experimentally using optical-shadowgraph imaging in the rotating frame for dimensionless rotation rates 6 ,V,20. Two cylindrical convection cells with radius-to-height ratios G540 and 23 were used. The cells contained CO2 at 33.1 bar and 16.6 bar… CONTINUE READING
