Bubble nucleation from gas cavities — a review
Abstract This review is concerned with the nucleation of bubbles in solutions supersaturated with a gas, in particular the bubble nucleation that occurs at specific sites, as a cycle. AExpand

The cycle of bubble production from a gas cavity in a supersaturated solution
Abstract Bubble nucleation, classified according to the review by Jones et al. (Adv. Colloid Interface Sci. 80 (1999) 27–50) as type IV non-classical, was examined in this study. Trains of bubblesExpand

A generalized empirical description for particle slip velocities in liquid fluidized beds
Abstract An empirical equation for calculating the slip velocity of a species in any homogeneous suspension is proposed. The Richardson and Zaki (1954, Trans. Inst. Chem. Engng, 32, 35–53) andExpand

Dense medium separation using a teetered bed separator
Abstract A Teetered Bed Separator (TBS) was used autogenously, and with a range of media, to study the dense medium separation of a coal feed slurry, −2.00+0.375 mm in size. The feed slurry consistedExpand

Performance of the reflux classifier for gravity separation at full scale
Abstract The Reflux Classifier (RC) is a fluidized bed separator capable of operating at high hydraulic loadings due to the presence of parallel inclined plates within the system. When the fluidizedExpand

Segregation of hydraulically suspended particles in inclined channels
The hydrodynamic transport of particles of different densities along inclined channels was examined using the reflux classifier (RC), a novel system consisting of a set of parallel inclined platesExpand

The effect of surface fog on the transmittance of light
Abstract It is shown theoretically that surface fog can reduce the transmittance of normally incident light through transparent materials from about 90% to nearly 50%. This result is also confirmedExpand

Solid–solid contacts due to surface roughness and their effects on suspension behaviour
Solid–solid contacts due to microscopic surface roughness in viscous fluids were examined by observing the translational and rotational behaviours of a suspended sphere falling past a lighter sphereExpand

  • 1 August 2005
This note provides a conceptually simple derivation of the Kelvin equation, based on the principles of hydrostatics, rather than the more elegant and abstract thermodynamic approach of equating chemical potential of each of the phases. Expand

Application of closely spaced inclined channels in gravity separation of fine particles
Abstract This paper is concerned with the gravity separation of fine particles in a Reflux Classifier, a fluidized bed device with a system of parallel inclined channels located above. A significantExpand
