Abstract :

The most important factor in the formation of impulse waves in the reservoir of the dam is caused by the landslide of the walls of the dam reservoir, because these waves, which are known as impulse waves, are very large and destructive. The importance of comprehensive studies regarding the sliding of objects and falling into water and the formation of impulse waves has caused many researchers to conduct research on this scientific phenomenon. Numerical modeling is the most suitable method for investigating the movement of floating, submerged and submerged objects in water, both in terms of engineering and economics. Among the well-known numerical modeling that can be used in the action of fluid and structure and the propagation of impulse waves, we can use finite element method, boundary element method, fluid volume method, finite difference method, and finite volume method. And the hydrodynamic method of smooth particles pointed out. In this article, in order to numerically investigate the waves resulting from solid and granular mass sliding, the general steps of the modeling method in FLOW-3D software will be presented. Also, the output results of the numerical solution of the slip wave model for solid and granular masses have been researched and investigated with the help of FLOW-3D software.
