WebNote that large-scale flow in Rayleigh–Benard convection exists not only in the´ very turbulent state but also near the onset of convective motion where the Rayleigh number Ra is just above the critical value for convection. For example, Charlson & Sani (1971) and Buell & Catton (1983) have made a linear stability analysis of a Web3.1.3. Rayleigh-Benard Convection. Consider a thin layer of fluid of thickness d and infinite horizontal extent. The lower surface is maintained at a temperature D T above that of the …

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 … cyndi\\u0027s list of genealogy sites
