Absence of Evidence for the 'Ultimate' State of Turbulent Rayleigh-B\'enard Convection
Charles R. Doering
TL;DR
This paper critically examines a previous claim that a specific turbulent convection regime was achieved, and finds no supporting evidence in the experimental data presented.
Contribution
It provides a rigorous analysis showing that the claimed 'ultimate' regime in turbulent Rayleigh-Bénard convection was not substantiated by experimental data.
Findings
No evidence for the 'ultimate' regime in the analyzed data
Challenges previous claims of reaching the 'ultimate' state
Highlights the need for more conclusive experimental validation
Abstract
The claim by He et al. [Physical Review Letters 108, 024502 (2012)] that their experiment reached the 'ultimate' regime of turbulent Rayleigh-B\'enard convection is not justified by their data.
