What is the final state of turbulence when the driving parameter approaches to infinity? For thermal turbulence, in 1962, Kraichnan proposed a so-called ultimate scaling dependence of the heat transport (quantified by the Nusselt number Nu) on the Rayleigh number (Ra), which can be extrapolated to arbitrarily high Ra. The existence of Kraichnan ultimate scaling has been intensively debated in the past decades. In this work, using a supergravitational thermal convection system, with an effective…

Multiple scaling in the ultimate regime of thermal convection
Very different types of scaling of the Nusselt number Nu with the Rayleigh number Ra have experimentally been found in the very large Ra regime beyond 1011. We understand and interpret these results
Turbulent convection at very high Rayleigh numbers
Investigating thermal transport over eleven orders of magnitude of the Rayleigh number, using cryogenic helium gas as the working fluid, finds no evidence for a transition to the Ra1/2 regime, and studies the variation of internal temperature fluctuations with Ra, and probe velocity statistics indirectly.
Transition to the Ultimate Regime in Two-Dimensional Rayleigh-Bénard Convection.
For the first time in numerical simulations, it is revealed how the emission of thermal plumes enhances the global heat transport, leading to a steeper increase of the Nusselt number than the classical Malkus scaling Nu∼Ra^{1/3} [Proc. R. Soc. A 225, 196 (1954)PRLAAZ1364-502110.0197].
Supergravitational turbulent thermal convection
This work presents a novel approach to boost the Rayleigh number in thermal convection by exploiting centrifugal acceleration and rapidly rotating a cylindrical annulus to reach an effective gravity of 60 times Earth’s gravity.
Scaling in thermal convection: a unifying theory
A systematic theory for the scaling of the Nusselt number Nu and of the Reynolds number Re in strong Rayleigh–Bénard convection is suggested and shown to be compatible with recent experiments. It
Experimental study of convection in the compressible regime
An experiment of thermal convection with significant compressible effects is presented. The high-gravity environment of a centrifuge and the choice of xenon gas enable us to observe an average
Classical 1/3 scaling of convection holds up to Ra = 1015
By direct numerical simulations of three-dimensional turbulent Rayleigh–Bénard convection flows in a slender cylindrical cell of aspect ratio 1/10, it is shown that the Nusselt number—the dimensionless measure of heat transport—follows the classical power law of Nu.
On the triggering of the Ultimate Regime of convection
Rayleigh-B\'enard cells are one of the simplest systems to explore the laws of natural convection in the highly turbulent limit. However, at very high Rayleigh numbers (Ra > 1E12) and for Prandtl
Turbulent Thermal Convection at Arbitrary Prandtl Number
The mixing‐length theory of turbulent thermal convection in a gravitationally unstable fluid is extended to yield the dependence of Nusselt number H/H0 on both Prandtl number σ and Rayleigh number
Aspect ratio dependence of the ultimate-state transition in turbulent thermal convection
It is pointed out that experimental Ra * values do indeed show a strong Γ dependence with Ra * well above 1 0 15 for Γ = 0.1, and that sidewall stabilization, and thus Ra * , is expected to increase with decreasing Γ.
