WebApr 11, 2024 · Here we investigate experimentally the complete freezing process of water with dissolved salt in a standard natural convection system, i.e. the prototypical Rayleigh–Bénard cell. Due to the presence of a mushy phase, the studied system is considerably more complex than the freezing of fresh water in the same conditions (Wang … WebApr 26, 2006 · An experimental study of Rayleigh-Bénard convection in helium gas at roughly 5 K is performed in a cell with aspect ratio 1. Data are analysed in a ‘hard turbulence’ region (4 × 10 7 < Ra < 6 × 10 12) in which the Prandtl number remains between 0.65 and 1.5.The main observation is a simple scaling behaviour over this entire range of Ra.
WebWe test these scaling arguments with data from laboratory and numerical experiments. Adequate agreement is found between theory and experiment, although there is a paucity of convection data for low . ... Heat Transport in Low-Rossby-Number Rayleigh-Bénard Convection.

But the experiment made by Bénard inspired Lord Rayleigh (J.W. Strutt) who in 1916 derived the theoretical
WebIt has been possible toperform a study, in fluorocarbon, at high Rayleigh number and to propose a discussion onthe transition to the "ultimate" regime of Rayleigh-Bénard convection by comparing with theliterature data. In parallel, the cryogenic Rayleigh-Bénard experiment has been developed toperform the same type of measurement in liquid helium.
