Characterization of Bubble Size Distributions within a Bubble Column [PDF]

open access: yesFluids, 2018
The current study experimentally examines bubble size distribution (BSD) within a bubble column and the associated characteristic length scales. Air was injected into a column of water via a single injection tube.

Lorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions [PDF]

open access: yesEntropy, 2009
Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy.
