NUMERICAL INVESTIGATION OF TURBULENT BUBBLY FLOW UNDER BREAKING WAVES

[摘要] We establish a framework for describing the spatial and temporal distribution of entrained air bubbles under breaking surface waves.The computational framework is based on a large eddy simulation (LES) in 3-D together with a VOF treatment of the air-water interface.An Eulerian multiphase approach is used in order to track the entrained bubbles as a number density distribution.Examples of numerical results for breaking periodic surf zone waves are illustrated.
