“…A low gas concentration in a liquid is usually a specific condition in a liquid-gas flow. In the likes of oil recovery, the chemical industry, and nuclear plants, separation is necessary to reduce the problems associated with the handling of two-phase mixtures, since single-phase streams are safer and easier to transport [9,25]. More importantly, liquid-gas separation is used for gas recovery in some processes.…”

The evolution of a polydisperse bubble cloud is analyzed by means of computational fluid dynamics. Gravity-driven bubble flows in a column with a circular cross-section as well as a downward flow in a long vertical pipe are numerically investigated. A method employed in the simulations is based on the Euler-Euler description of the multiphase medium. An inhomogeneous multiple-size group (MUSIG) model is used to describe the bubble size distribution. The formulated approach provides detailed description of the bubble flow structure including variation of the bubble size distribution.
