Adaptive Lattice Boltzmann simulations of free-surface flows
XVI International Conference on Computational Methods in Water Resources
2006
2006
Recently Lattice-Boltzmann (LB) methods have matured as complementary models and
simulation approaches for solving complex flow problems in engineering.
In our work we extend an existing laminar free surface LB model recently developed
by Koerner et al. by a Large Eddy model to describe turbulent flows and validate our
model by threedimensional computations of a rigid body impact on a shoreline and the
resulting wave generation. The results are compared to experimental and numerical
data obtained by Liu et al.
In addition, we present an adaptive 3D simulation of the classical dam break problem.
