Numerical simulations of sloshing flows with an elastic baffle using a SPH-SPIM coupled method

Three‐dimensional weakly compressible moving particle simulation coupled with geometrically nonlinear shell for hydro‐elastic free‐surface flows

“…The overall trends of the computed displacements agree well with the experimental one and performed slightly better than PFEM results, although small discrepancy occurs near $$$ t=0.5 $$$ s and the experimental motion is not numerically well reproduced. This discrepancy was also found in the numerical results from others 7,12,45,59,101,102 . These differences can be related to some uncertainties in the experiments.…”

“…The mesh-free particle-based (Lagrangian) methods, such as smoothed particle hydrodynamics (SPH) 1,2 and moving particle semi-implicit/simulation (MPS), 3 are very effective to model violent FSI free-surface flows with large interfacial deformation and fragmentations. 4,5 These methods have been widely developed in the context of hydroelasticity 6,7 and many others as reviewed by Gotoh et al, 8 with some focused on parallel computing in graphics processing units, 9,10 and applied to solve related problems such as sloshing, 11,12 slamming, 13 dam breaking, 14 tsunami, 15,16 structure failures, 17,18,19 composite structures, 20 and biomedical engineering. 21 Nevertheless, since uniform spatial resolution is usually adopted in the fluid domain for large-scale FSI problems involving complex or thin structures, huge computational efforts associated with high-resolution models are demanded.…”

A Review of SPH Techniques for Hydrodynamic Simulations of Ocean Energy Devices

“…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]).…”

Multiphase smoothed particle hydrodynamics modeling of forced liquid sloshing

“…Green and Peiró 16 investigated a typical example of liquid sloshing in tanks with low filling levels and high stretching ratios. Hu et al 17 applied the SPH‐smoothed point interpolation method (SPIM) coupled method to perform flow‐control studies by adding an elastic baffle inside the tank. Zhang et al 18 also investigated the sloshing mitigation with elastic baffles by employing the coupling strategy of the smoothed finite element method and an improved SPH.…”
