Bubbly flows are ubiquitously found in natural systems and are widely used in (bio)-chemical and energy-producing processes. A variety of design options, ease of maintenance, and a large operability window make bubble columns a commonplace across industries, ranging from oil processing to biotechnology and electrolyzers. Despite their wide...

In this work, the rise characteristics of a single H<sub>2</sub> bubble, in the ellipsoidal regime, in (i) water, (ii) single electrolyte (2 M, 4.5 M NaCl) solution and (iii) various concentrations of electrolyte mixture (up to 6.4 M of 1:5 weight fraction NaCl-NaClO<sub>3</sub>), have been studied, at temperatures up to 80°C. Our results...

In this work, the effect of an electrolyte (up to 2 M of NaCl dissolved in water) on a homogeneous dense bubbly flow, in an airlift bubble column, is studied using nonintrusive techniques. X-ray and high-speed imaging are used to investigate the bubble size distribution, the local and the global gas-fraction profiles. The major effect of the...
