Abstract

In this study, an air entrainment model based on the turbulence production and laboratory measured air bubble size spectrum is incorporated into a two-dimensional numerical model (NEWFLUME) to investigate the bubble plume dynamics under breaking processes. The model solves the Reynolds equations for turbulent flow fields and employs the volume-of-fluid (VOF) method to track free surfaces. The integral properties of bubble plume are investigated and compared with the experimental data. The void fraction distributions are examined and the relationship between the void fractions and turbulence intensity is discussed.
