In this paper, a two-phase Smoothed Particle Hydrodynamics (SPH) method is used to
simulate the fluid–structure interactions with violent deformation of the free surface. An
improved solid boundary treatment is proposed based on the accurate pressure
interpolations of the inner fluid particles. The model performance is validated by sloshing in
a water tank and dam break flow impact on a vertical wall. In the practical model
applications, a two-dimensional wedge entry into the static water is studied, for which the …
