Rayleigh-Bénard convection using cryogenic nitrogen at high Rayleigh numbers
Abstract
We leverage the variability of thermophysical properties of cryogenic nitrogen gas to span Rayleigh numbers between 108 and 1014 and Prandtl numbers between 1 and 100, to study heat transport in a Rayleigh Bénard system of cylindrical geometry with unity aspect ratio. Specific focus is placed on controlling fluid properties to maintain the validity of the Boussinesq approximation.
