Numerical Analysis of Pressures on Rigid Structures Using the Smoothed Particle Hydrodynamics Method

The paper presents a numerical analysis of hydrodynamic pressures on rigid structures caused by dynamic base excitation. First, the model for the fluid simulation, based on the numerical approach called the Smoothed Particle Hydrodynamics (SPH) method, is presented. Then, the described model is used to calculate the pressures on rigid structures. In the performed analysis, the structures of various geometries (a rectangular tank with vertical sides, rectangular tanks with one inclined side of constant slope and a cylindrical tank) are exposed to simple harmonic horizontal base excitations. The obtained hydrodynamic pressures on the sides of the tanks are compared with analytical and other numerical solutions.
