Bubble size distribution in bubble columns

The Canadian Journal of Chemical Engineering, 1990
AbstractThe bubble size distributions are measured for the air‐water system as a function of air velocity at room temperature in two bubble columns. High speed cinephotography and fiber optic probe techniques are used to measure the bubble size. Our limited measurements suggest that the bubble size may be independent of gas velocity in the range 3.6 to

Bubble-size distributions in foams

Advances in Colloid and Interface Science, 1992
Abstract Bubble-size distributions in foams can be used to study foam properties and to distinguish between the physical processes that contribute to the breakdown of the foam. These processes are drainage, coalescence and disproportionation. A new Foam Analyzer was developed to measure various foam characteristics like the rate of drainage, the rate

Bubble distribution and behaviour in bubbling fluidised beds

Chemical Engineering Science, 2007
Abstract Bubble spatial distribution is a prime determinant of the process properties within a fluidised bed, and is coupled to and governed by the flow supply. Bubbles induce heterogeneity and the gas within them rises through the bed without much interaction with other phases.

Acoustics of bubbly sediments with a distribution of bubble sizes.

The Journal of the Acoustical Society of America, 1991
A model for a saturated, porous elastic medium containing bubbles of gas [J. Acoust. Soc. Am. 73, 409–417 (1983)] has been combined with a model for a bubbly liquid with a bubble population whose radii vary continuously over a known distribution [J. Acoust. Soc. Am. Suppl. 1 88, (1990)] to obtain an acoustical model for saturated sediments containing a
