“…One typical method is to use the particle-mesh coupling strategy where the SPH solver is usually adopted for the fluid portion, while the mesh solver is adopted for the structure portion. Regarding this coupling measure, extensive works can be found in the literature, such as SPH-FE (Finite Element) (see, e.g., [200][201][202][203][204]), the Smoothed Point Interpolation Method (SPH-SPIM) (see, e.g., [205,206]), and MPS-FE (see, e.g., [76,[207][208][209]). Another method is totally based on Lagrangian particles either for the fluid solver or the structure solver, e.g., SPH-TLSPH (Total Lagrangian SPH) (see, e.g., [210][211][212][213][214]), the Reproducing Kernel Particle Method (SPH-RKPM) (see e.g., [215,216]), and SPH-PD (Peridynamics) (see, e.g., [217][218][219][220]).…”

This article is dedicated to providing a detailed review concerning the SPH-based hydrodynamic simulations for ocean energy devices (OEDs). Attention is particularly focused on three topics that are tightly related to the concerning field, covering (1) SPH-based numerical fluid tanks, (2) multi-physics SPH techniques towards simulating OEDs, and finally (3) computational efficiency and capacity. In addition, the striking challenges of the SPH method with respect to simulating OEDs are elaborated, and the future prospects of the SPH method for the concerning topics are also provided.

“…However, this approach cannot simulate structural deformation and stress distribution well. In light of this, growing attempts have been made to develop grid-particle coupling methods (e.g., MPS/FEM [20][21][22][23][24] and SPH/FEM [25,26]) to take full use of their advantages, where the grid-based and particle-based methods are, respectively, adopted to account for structural deformation and fluid flows.…”

This work aims to propose an efficient MPS/FEM coupling method for the simulation of fluid–structure interaction (FSI), where the MPS and FEM are respectively employed to account for fluid flows and structural deformation. The main idea of our method is to develop a multi-scale multi-resolution MPS method for efficient fluid simulations in the context of MPS/FEM coupling. In the developed multi-scale MPS method, the fluid domain is discretized into particles of different resolutions before calculation, where particles close to the interest domain will be discretized into high resolution, while the rest are discretized into low resolution. A large particle interacting with small particles is divided into several small particles virtually, and weight functions are redefined to maintain the simulation stability. A bucket-sort-based algorithm is developed for the fast search of multi-resolution neighboring particles. The capacity of a newly proposed ghost cell boundary model is further enhanced, so as to accurately treat wall boundary problems with particles of different resolutions. On this basis, the multi-resolution MPS method is coupled with the FEM for FSI simulations. Finally, several numerical examples are conducted to demonstrate the accuracy and efficiency of the development method.

“…Experiments on the impact loads on a flat plate were conducted and generated key findings on trapped air and its effect on impact pressure [15]. In recent years, another significant study investigating water wave impact was done by taking the elasticity of the plate into consideration [16]. Further developments on wave impact have been discussed by others [17] who have investigated the transient properties of the flow field of a wave slamming a superstructure of an open structure, and the instantaneous velocity field of the impacting wave was obtained using a particle image velocimetry (PIV) system.…”

Water wave impact on a wet deck is an important issue in ocean engineering, and the plate-shaped structure in the splash zone tends to suffer tremendous impact loads. This work presents a method for predicting the wave slamming uplift force on a fixed plate with different inclined angles. Both numerical simulation and the scale model test of the wave impact loads on an inclined plate were performed, and a good agreement was obtained. In addition, the influence of three important wave parameters on the slamming uplift force was systematically investigated: relative deck width B/LS, relative wave height Δh/H1/3, and the plate’s inclined angle α. The results indicate that the three parameters can significantly influence the wave slamming uplift force. Finally, a developed empirical equation is proposed for estimating the wave slamming uplift force on the inclined plate.
