Rayleigh benard convection pdf
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 … WebINTRODUCTION. Convection due to nonuniform heating is, without overstatement, the most widespread type of fluid motion in the Universe. It plays also an important role in various …
