Lattice Boltzmann method for simulating impulsive water waves generated by landslides

Impulsive water waves generated by landslides impose severe damage oncoastal areas. very large mass ows in the ocean can generate catastrophic tsunamis.preventing damage to dams and coastal structures, and saving the lives of local peopleagainst landslide-generated waves, has become an increasingly important issue in recentyears. numerical modeling of landslide-generated waves is a challenging subject in cfd.the reason lies in the diculty of determining the interaction between the moving solidsand sea water, which causes complicated turbulent regimes around the moving mass andat the water surface. submarine or aerial types of landslide can further complicate theproblem. up to now, a number of numerical approaches have been proposed for predictingthe behavior of ow during and after mass movement. in this study, a lattice boltzmannmethod (lbm) based-code is employed for analyzing and simulating the impulsive waterwaves generated by landslides. four experimental cases of submerged and aerial landslideshave been modeled to investigate the eciency and accuracy of the lbm code, and theobtained results are veried against experimental observations. the results indicate thecapability of lbm in simulating complicated ow elds and demonstrate its superiorityover numerical methods used so far, such as sph and rans.
