Liquid Mixing and Mass Transfer in a Packed Bubble Column

A Stochastic Analysis of Liquid Mixing in Bubble Column

In the present study, the mixing of liquid phase in bubble column is analysed by an entropy theory. The Kolmogorov entropy factor depending on the operating parameter is estimated to evaluate the concentration profile of the solute dispersed in the dynamic two-phase system. The intensity of mixing is enunciated by the Kolmogorov entropy parameter and correlated with the degree of mixing in the ...

Heat Transfer in a Column Packed With Spheres

The purpose of the study is to investigate average and local surface heat transfer coefficients in a cylinder packed with spheres. Here the term «local» applies to a single sphere within the bed. Averages are derived from the sixteen different spheres that were instrumented and distributed throughout the bed. The experimental technique consisted of introducing a step - wise change in the temper...

Mixing in Bubble Column and Airlift Reactors

M ixing behavior of three geometrically equivalent 0.06 m bubble column and airlift photobioreactors was compared for use in microalgal culture. Mixing was characterized in terms of the axial dispersion coefficient, mixing time, circulation time and Bodenstein number. Measurements were reported in tap water and sea water, as used in growing microalgal biomass. Compared with the two airlift reac...
