“…As can be seen from Figure 3, the multiphase results show an underestimation of the water column movement by a factor of 0.7, while the single-phase can match the experiment quite well with a factor of 0.92. This result may happen because the dualSPHysics models the air as weakly compressible, which is inline with Lu et al, 2021. Because of that, the exitance of air suppresses the extent to which the water column can move. This is proven by the fact that singlephase results, which model the air above the water as a void, was able to closely match the experimental results.…”

A numerical model of a vertical breakwater integrated with wave absorption chamber has been tested against regular wave in a virtual wave flume. The open source Smoothed-Particles Hydrodynamics, or SPH, (Lagrangian type) software called DualPSHysics was deployed for the simulation. Both the multiphase (air-water) and single-phase (water only) fluid were considered and compared with an experimental result. Single-phase and multiphase capture the water column elevation in an open chamber within a ratio of 0.92 and 0.70, respectively, when compared to experiments. However, single-phase is not able to capture the fully closed chamber effect. It is found that inside the fully closed chamber, the multiphase SPH captures the maximum (compressed) water elevation well but overestimates the air compression by a factor of 1.5.
