Sabilization of Free Surface Flows by Incompressible Lattice Boltzmann Method

Abstract

 Lattice Boltzmann Method (LBM) has been developed as a new, robust and efficient model to solve the fluid dynamics. In this study, we stabilize LBM on free surface flows applying incompressible model which is simple low cost. The model was verified in the dam-break flow experiment over a 3-D isolated block. The model results are in good agreement with the experimental data, including the movement of free surface of water body, and splash against the block. Through the model verification, we found that our model can be applied to simulate three dimensional behavior of tsunami inland penetration.
