| Popis: | A prediction (solid line) for the ultimate-state transition Rayleigh-number, with its pre-factor adjusted to fit the experimental value for a Prandtl number Pr = 0.82, passes through the DNS estimate for Pr = 0.021. Cryogenic observations of transitions (solid circles) fall well below this line. |
