    2019-2-1 · Rising bubbles. Bubbles in the ocean are abundantly caused by breaking waves in surface waters (Blanchard and Syzdek, 1970, Czerski et al., 2011, Garbalewski and Marks, 1987, Monahan et al., 1983, Woodcock, 1953) and rain drop impact upon the water surface (Blanchard and

    Rising bubbles Journal of Fluid Mechanics

    2006-4-20 · The shape of a rising bubble, or of a falling drop, in an incompressible viscous fluid is computed numerically, omitting the condition on the tangential traction at the bubble or drop surface. When the bubble is sufficiently distorted, its top is found to

    The behavior of rising bubbles covered by particles

    2019-6-1 · A bubble rises mainly because of the buoyancy force, which acts against the drag force. The density and viscosity of the gas in a bubble also influence the bubble behavior, but these effects are not as significant as the drag force and buoyancy force exerted on the rising bubbles [2], [3].

    Rising bubbles enhance the gelatinous nature of the

    2019-5-8 · Bubbles rising through the water column are known to scavenge organic material and microorganisms, and transport them through the air–sea interface after bursting. This mechanism has important implications for air–sea exchange processes.

    Shape Oscillations of Rising Bubbles SpringerLink

    The paper details results from an experimental study on bubbles rising in still tap water. Shape and motion parameters of the bubbles were measured using a combination of high speed cinematography and digital image processing.

    Free-rising bubbles bounce stronger from mobile than

    2020-5-7 · Recently it was reported that interface mobility of bubbles and emulsion droplets can have a dramatic effect not only on the characteristic coalescence times, but also on the way bubbles and droplets bounce back after collision [Sci. Adv. 2019, 5, eaaw4292]. Experiments with free-rising bubbles in a pure perfluorocarbon liquid showed that collisions involving mobile interfaces result in

    Adsorption Kinetics of Various Frothers on Rising

    The kinetics of frother’s adsorption on the surfaces of rising bubbles was studied theoretically. It was established that PPG 200, MIBC, BTEG, BDPG, and BTPG, in accordance with their surface tension data, reach adsorption equilibrium within milliseconds (weak frothers), while PPG 400 and PPG 600 reach adsorption equilibrium in 9.7 s and 15.4

    Modeling and simulation of convection-dominated

    The gas-liquid interface of rising bubbles deforms dynamically due to the interaction of pressure, viscous forces, surface tension, and body forces. For multiphase-contactors, like bubble column reactors, it is of the highest interest to predict how the gas dissolves and reacts in the liquid phase. This mass transfer process strongly depends on convection-dominated, extremely thin species
