Resum
Two-dimensional nonlinear convection in a vertical rotating cylindrical annulus with flat adiabatic stress-free lids, heated from the inside and with radial gravity, is numerically analyzed for a low value of the Prandtl number, s = 0.025. When the Rayleigh number exceeds a critical value, the conduction state becomes unstable and steady columns parallel to the axis of rotation, and characterized by a finite integer azimuthal wavenumber, n, are the preferred form of convection at the onset for l...
