“…Meanwhile, another revised SPH method was adopted to numerically study the total horizontal force on perforated caissons, described the velocity vector of water particles entering and exiting the wave chamber, and analyzed the distribution of each component of the total horizontal force (Tang et al, 2017b). The open-sourced computational fluid dynamics software (OpenFOAM), is used for investigating the wave loads on boxes and the time series of the free surface of water from their influencing factor, such as spectral peak periods, wave amplitudes, horizontal positions and initial velocities (Gao et al, 2022;Gao et al, 2023). From the microscopic perspective, a series of comparison were made to study the effects of three-dimensional mixed nanofluid flow (Zhang et al, 2022).…”

The Smoothed Particle Hydrodynamics (SPH) method modified by Corrective Smoothed Particle Method (CSPM) and Riemann solution is employed to simulate the interaction between double-chambered perforated caissons and waves. The accuracy and applicability of the numerical method are verified by the theoretical values and experimental data through comparisons. The effects of the top cover height s, the width of the wave dissipation chamber B and the perforated rate μ on the wave surface η or wave pressure p of the caisson are numerically analysis. The results show that under the calculated wave conditions, the top cover height s and perforated rate μ are significant factors affecting the wave dissipation performance of the caisson, while the width of the wave dissipation chamber B has little effect on the wave surface η. In the meanwhile, with the increase of the top cover height s, the wave pressure p on the front perforated plate and the back wall at the static water level gradually decreases, and the wave pressure p on the back perforated plate first decreases and then increases. In addition, the modified SPH method is also used to explore the changes of the pressure field and the velocity field of water particles, tracing the instantaneous velocity of water particles at different positions at different time, and describe the motion state of water particles, which provides effective facilitates for investigating the interaction between double-chambered perforated caissons and waves.
