Turbulent, rapidly rotating convection has been of interest for decades, yet there exists no generally accepted scaling law for heat transfer behaviour in this system. WebIn this paper, we apply a scaling analysis of the maximum of the probability density function (pdf) of velocity increments, i.e., p max (τ) = max Δ u τ p (Δ u τ) − τ − α, for a velocity field of turbulent Rayleigh-Bénard convection obtained at the Taylor-microscale Reynolds number Re λ ≈60. The scaling exponent is comparable with that of the first-order velocity structure …
