INTERNATIONAL JOURNAL OF TRANSPORT PHENOMENA, ISSN: 1028-6578, Vol.1, No.3, pp.173-190, 1999 Streszczenie:
The three-dimensional instability of an axisymmetric natural convection flow is investigated numericaUy using a global spectral Galerkin method. The linear stability problem separates for different azimuthal modes. This aUowsus to reduce the problem to a sequence of 2D-like problems. The formulation of the numerical approach and several test calculations are reported. The numerical results are successfully compared with an experiment on natural convection of water in a vertical cylinder, which shows an axisymmetry-breaking instability with a high azimuthal wavenumber.
