| Abstract | Dam break analysis plays a key role in hydraulics engineering for safety. In this paper, 3D numerical simulations ofdam-break flow using Finite Volume and Lattice Boltzmann methods are studied and discussed. All the computation in this workis achieved by ANSYS Fluent and XFlow. Large Eddy Simulation (LES) is employed as the turbulence model and the freesurface flow is captured using a Volume of Fluid (VOF) model in the two simulation approaches. Results are then compared withexperimental data on dam-break flow through complex obstacles. This experimental data is obtained by a high-speed cameraaiming to capture free surface waves. The comparison between the experimental data and simulations shows good tendency.However, LBM requires less computational time. |
