Plume structure in high-Rayleigh-number convection
TL;DR: In this paper, the authors show that the near-wall structure is made of laminar natural-convection boundary layers, which become unstable to give rise to sheet plumes, and conclude that in the presence of a mean wind, the local nearwall boundary layers associated with each sheet plume in high-rayleigh-number turbulent natural convection are likely to be Laminar mixed convection type.
Journal ArticleDOI
Motion of drops on inclined surfaces in the inertial regime
TL;DR: In this article, the authors present experimental results on high-Reynolds-number motion of partially nonwetting liquid drops on inclined plane surfaces using: (i) water on fluoro-alkyl silane (FAS)-coated glass; and (ii) mercury on glass.
Journal ArticleDOI
On the scaling of jetting from bubble collapse at a liquid surface
TL;DR: In this article, scaling laws for the jet velocity resulting from bubble collapse at a liquid surface which bring out the effects of gravity and viscosity were presented. But the actual dependence of on is determined by the gravity dependency of the bubble immersion (cavity) depth which has no power-law variation.
Journal ArticleDOI

TL;DR: In this article, the authors present planforms of line plumes formed on horizontal surfaces in turbulent convection, along with the length of plumes measured from these planforms, in a six decade range of Rayleigh numbers (10(5) < Ra < 10(11)) and at three Prandtl numbers (Pr = 0.7, 5.2, 602).
Journal ArticleDOI
Evolution and breaking of parametrically forced capillary waves in a circular cylinder
TL;DR: In this paper, the authors investigated the evolution of the wave patterns from the instability to the wave-breaking threshold in a forcing frequency range (f = ω/2π = 25-100 Hz) that is around the crossover frequency from gravity to capillary waves (ω ot /2 ≤ ω 2π ≤ 4ω ot ).
