✦ Synopsis

The gas-liquid slug flow pattern exists over a broad range of flow rate space at reduced gravity conditions and for that reason is expected to be widespread in many space applications. The objective of this work was to develop a model predicting the characteristics of slug flow at reduced gravity including the bubble length, shape, velocity and other properties of the slug flow. Observations derived from low-gravity experiments suggested the use of a boundary layer-type approach. Multiple solutions exist, and a criterion for selecting the solution which corresponds to experimental observation is indicated.

## Abstract The distribution of gas and liquid in a gas–liquid two‐phase slug flow was measured using semi‐supermultiple point‐electrode probes. Based on the measurements, the wake zone behind a gas slug and the low void‐fraction zone in a liquid slug were defined, and the void fractions of the two

## Abstract A computational fluid dynamics–population balance model (CFD‐PBM) coupled model was developed that combines the advantages of CFD to calculate the entire flow field and of the PBM to calculate the local bubble size distribution. Bubble coalescence and breakup were taken into account to
