Turbulent Rayleigh-Benard convection in low Prandtl-number fluids
Description
An experimental investigation of Rayleigh-Benard convection in liquid sodium has been performed in cylindrical test cells with aspect ratios between 20 and 4.6 for a range of Rayleigh numbers 104 106. An instability in these thermal boundary layer triggers a new mode of large scale fluctuating motion. The analysis of the temperature time signals shows that the temperature field behaviour up to a Rayleigh number Ra ∝ 5 . 106 is essentially dissipative. (orig.)
