Description

Recently, Ahlers et al. [1] experimentally and numerically found logarithmic temperature profiles not only in the ultimate regime of turbulence, but also in the “classical regime” for Rayleigh numbers as low as 1e10. In this talk we will try to rationalize this surprising behavior, based on a novel viewpoint of plume-driven flow.
