Abstract
We report on the experimental results for heat-transport measurements, in the form of the Nusselt number Nu, by turbulent RayleighBnard convection (RBC) in a cylindrical sample of aspect ratio DL0.50 (D1.12m is the diameter and L2.24m the height). The measurements were made using sulfur hexafluoride at pressures up to 19bar as the fluid. They are for the Rayleigh-number range 31012Ra1015 and for Prandtl numbers Pr between 0.79 and 0.86. For Ra
