Abstract

An experimental study is described of various cellular convection patterns in cylindrical containers at supercritical Rayleigh numbers. The fluid containers are heated from below and as the Rayleigh number is slowly increased the convection patterns undergo a series of bifurcations to nonaxisymmetric configurations. The form of convection depends on both the Rayleigh number and aspect ratio of the container. The observations are discussed in the light of current understanding of pattern-forming phenomena.
