Taking full account of the liquid viscosity, surface tension and other factors, a detailed numerical simulation using VOF method was carried out to study the dynamic behavior of bubbles in still water, and obtained the rising path, deformation process and speed changes. The numerical results were compared with experimental data, and gained good result. It shows the results of this study can provide...
This study presents the direct numerical simulations (DNS) of bubbly wake flows. The DNS with Lagrangian particle dynamics (LPD) model is applied to the cases of bubble dispersion over a cylinder and a hydrofoil. The model validation is performed on the experimental data for the bubble behaviour in the wake of a circular cylinder. It is confirmed that the simulated distributions of bubble stream agree...
