The fluid-structure interaction algorithm (FSI) by meshless methods is presented. Dynamics of fluid is simulated by Smoothed Particle Hydrodynamic Method (SPH) and, for moving solid bodies, Discrete Element Method (DEM) is used. The interaction between the fluid and solid bodies is determined by additional contact forces in motion equations for SPH and DEM, respectively. The special condition of contact algorithm is considered for each pair of liquid and solid particles within the interface, the area. The features and calculation procedures of these numerical methods are described. During simulations, the dam break experiment was carried out. The fluid-body interactions are considered according to the boundary conditions introduced by dynamic boundary particles. Obtained results show that the algorithm gives good agreement with the physical experiment.
Keywords: smooth particle hydrodynamic, discrete element method, solid body dynamic, fluid-structure interaction.
