Turbulent convection experiment at high Rayleigh number to support CAP1400 IVR strategy

The experiments are divided into two parts. Each part concerns 39 runs and 47 experimental conditions. Its corresponding results are obtained at middle Prandtl number (Pr = 7 for water) and the Nusselt number is found to be proportional to Ra0.315 in the range 3.93 × 108 < Ra < 3.57 × 1012. Furthermore, the experiment results can predict the relationship between axial and radial heat transfer well.
