Summary

It is found that the numerical experiments verify the flow features that are known from theoretical asymptotic analysis of this problem (valid for shallow spaces) only over a certain range of the parametric domain, and that this solution breaks down as the Rayleigh number is increased beyond 3000, when a bifurcation takes place and a new steady state is achieved, that of a multi-cellular type. The transient numerical experiments show that in the present parametric domain the single-cell circulation is not stable with respect to the Bénard instability one expects in fluid layers heated from below. The result is supported by recent experimental and numerical results reported on this problem.
