Lorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions [PDF]
Entropy, 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. It turns out that the temporal development of the entropy is preserved although characteristics of the histograms ...

Aqueous foams in microgravity, measuring bubble sizes
Comptes Rendus. Mécanique, 2023 The paper describes a study of wet foams in microgravity whose bubble size distribution evolves due to diffusive gas exchange. We focus on the comparison between the size of bubbles determined from images of the foam surface and the size of bubbles in ...

Analysis of bubble distribution in a multiphase rotodynamic pump
Engineering Applications of Computational Fluid Mechanics, 2019 Recent researches show that the pressure increment of a multiphase pump is affected by bubble size and distribution. In order to study the bubble distribution characteristics in such pumps, a novel approach describing the variable bubble size in the pump

Grain-size distribution of volcaniclastic rocks 1: A new technique based on functional stereology [PDF]
, 2012 The power of explosive volcanic eruptions is reflected in the grain size distribution and dispersal of their pyroclastic deposits. Grain size also forms part of lithofacies characteristics that are necessary to determine transport and depositional ...
