Abstract
We present measurements of the Nusselt number as a function of the Rayleigh number in cylindrical cells with aspect ratios ( is the diameter and is the height). We used acetone with a Prandtl number for . A fit of a power law over limited ranges of yielded values of from 0.275 near to 0.300 near . The data are inconsistent with a single power law for . For they are consistent with as proposed by Grossmann and Lohse for .
