Abstract
A set of closure relations for adiabatic bubbly flow has been collected that represents the best available knowledge and may serve as a baseline for further improvements and extensions to more general situations. Submodels for bubble forces, bubble-induced turbulence and bubble coalescence and breakup are considered. A preliminary validation of the model is presented by comparison to selected tests from the TOPFLOW database. Specific attention is paid to effects of polydispersity. Issues to be addressed in future work are discussed.
