Web10. apr 2024 · The SPH model is validated for flat, sloped, parabolic, and circular bottom tanks with screens at a low excitation amplitude and shallow water depths using existing linearized models introduced in Deng and Tait [21, 23]. The SPH model is validated at large amplitudes against available experimental data from [18, 27, 46] for different bottom ... Web25. apr 2024 · Besides the N-S equation, SPH assumes that pressure is a function of density through equation of state. Among various equations of state, the Tait equation of state is widely used in fluid mechanics [29,35], which is expressed as: WebThe Tait equation of state is applied to smoothed particles, and the material properties of the SPH particles representing the water, wavemaker, and mass-weighted damping zone are given in Table 2. how to use contactless card for first time
