Near-onset convection patterns in the spherical Bénard problem with l=2 critical


Bifurcation of convective patterns in a spherical shell of Boussinesq fluid is investigated using center manifold reduction at the onset of the instability of the l = 2 spherical harmonics. The existence and stability of patterns with D(2) and O(2) symmetry are determined using results from singularity theory and a complete classification is given as a… (More)
