Preliminary Assessments of Combined Effects of Surface Tension and Viscosity on Bubble Column Hydrodynamics
The present contribute reports results of combined effects of liquid features on the hydrodynamics of a lab-scale bubble column. In particular, the combined effects of viscosity - Newtonian fluid ? and surface tension were ...
