We present the results of a combined experimental and theoretical investigation of the vertical impact of a hydrophobic sphere with a water surface. Particular attention is given to characterizing… (More)

We describe three apparatus, known as the large, medium, and small apparatus, used for high-precision measurements of the Nusselt number N as a function of the Rayleigh number R for cylindrical… (More)

Measurements over the Rayleigh-number range 10 <∼ R <∼ 10 and Prandtl-number range 4.4 <∼ σ <∼ 29 that determine the torsional nature and amplitude of the oscillatory mode of the large-scale… (More)

We present high-precision measurements of the Nusselt number N as a function of the Rayleigh number R for cylindrical samples of water (Prandtl number σ = 4.38) with diameters D = 49.7, 24.8, and 9.2… (More)

Non-Oberbeck–Boussinesq (NOB) effects on the Nusselt number Nu and Reynolds number Re in strongly turbulent Rayleigh–Bénard (RB) convection in liquids were investigated both experimentally and… (More)

We present high-precision measurements of the Nusselt number N as a function of the Rayleigh number R for cylindrical samples of water (Prandtl number σ = 4.4) with a diameter D of 49.7 cm and… (More)

We used the time correlation of shadowgraph images to determine the angle Theta of the horizontal component of the plume velocity above (below) the center of the bottom (top) plate of a cylindrical… (More)

We report on the experimental results for heat-transport measurements, in the form of the Nusselt number Nu, by turbulent Rayleigh–Bénard convection (RBC) in a cylindrical sample of aspect ratio 0 ≡… (More)

Measurements of the Nusselt number Nu and of temperature variations DeltaTb in the bulk fluid are reported for turbulent Rayleigh-Bénard convection of a cylindrical sample. They cover the… (More)

We describe a pressure vessel for conducting experiments in helium (He), air, nitrogen (N2) or sulfur hexafluoride (SF6) under pressures of up to 19 bars, and facilities for the study of… (More)
