✦ Synopsis

Compared with single-phase laminar pipe flow, two-phase bubble-train flow shows a significantly increased rate of mass transfer between liquid and wall. The present work is a study of this effect over a wide range of the governing variables. The problem has been numerically simulated and experimentally examined using the copper dissolution method. Furthermore, a mathematical correlation for the Sherwood-number of the system is presented and the mechanism of transport enhancement is elucidated.

## Abstract An experimental method was developed for measuring the mass transfer in water/air/carbon dioxide systems with pH‐probes. Measurements of the mass transfer were made with respect to the parameters of desorption in bubble plumes. The investigations show a linear increase of the mass trans

The name bubble-train flow is used to identify the cocurrent flow of gas bubbles and liquid slugs through a capillary. A model was developed to analyze mass transfer between bubbles and liquid slugs during bubble train flow. This mass transfer model, derived from the equations of transport, is based

## Abstract Bubble columns are widely used in the chemical and biochemical industries. In these reactors a gaseous phase is dispersed into a continuous liquid phase thus the rising bubble swarm induces a circulating flow field. For the dimension of these reactors the local interfacial area and the
