“…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 three-dimensional fluid-structure interaction solver based on an improved weakly compressible moving particle simulation (WC-MPS) method and a geometrically nonlinear shell structural model is developed and applied to hydro-elastic free-surface flows. The fluid-structure coupling is performed by a polygon wall boundary model that can handle particles and finite elements of distinct sizes. In WC-MPS, a tuning-free diffusive term is introduced to the continuity equation to mitigate nonphysical pressure oscillations. Discrete divergence operators are derived and applied to the polygon wall boundary, of which the numerical stability is enhanced by a repulsive Lennard-Jones force.Additionally, an efficient technique to deal with the interaction between fluid particles placed at opposite sides of zero-thickness walls is proposed. The geometrically nonlinear shell is modeled by an unstructured mesh of six-node triangular elements. Finite rotations are considered with Rodrigues parameters and a hyperelastic constitutive model is adopted. Benchmark examples involving free-surface flows and thin-walled structures demonstrate that the proposed model is robust, numerically stable and offers more efficient computation by allowing mesh size larger than that of fluid particles.

“…The gradient model of momentum conservation (Tanaka and Masunaga, 2010), the mixed source term of Pressure Poisson Equation (PPE) (Tanaka and Masunaga, 2010;Khayyer and Gotch, 2011) and the Particle Shifting Technique (PST) (Khayyer et al, 2017;Duan et al, 2018) have been proposed, which significantly improve the stability and accuracy of incompressible particle-based method. Based on the above improvement, particle-based methods have been applied for the simulation of multiphase flows (Wen et al, 2021a(Wen et al, , 2021b(Wen et al, , 2021cXie et al, 2021b) and Fluid-Structure Interaction (FSI) (Gotoh et al, 2021;Xie et al, 2021a;Zhang et al, 2021). In the actual pipeline system, there are pumps rotating fast to lift the seawater and minerals.…”

In the process of deep-sea mining, the liquid-solid flows in the vertical transportation pipeline are very complex. In the present work, an in-house solver MPSDEM-SJTU based on the improved MPS and DEM is developed for the simulation of hydraulic conveying. Firstly, three examples including the multilayer cylinder collapse, the Poiseuille flow and two-phase dam-break are used to validate the precision of the DEM model, the pipe flow model and MPS-DEM coupling model, respectively. Then, the hydraulic conveying with coarse particles in a vertical pipe is simulated. The solid particle distribution is presented and investigated in detail. Finally, the coupling method is successfully applied for the simulation of the liquid-solid flows in a vertical pipe with rotating blades, which shows the stability of the solver under rotating boundary conditions. This fully Lagrangian model is expected to be a new approach for analyzing hydraulic conveying.

With the significant development of computer hardware, many advanced numerical techniques have been proposed to investigate complex hydrodynamic problems. This article aims to provide a detailed review of moving particle semi-implicit (MPS) techniques and their application in ocean and coastal engineering. The achievements of the MPS method in stability and accuracy, boundary conditions, and acceleration techniques are discussed. The applications of the MPS method, which are classified into two main categories, namely, multiphase flows and fluid-structure interactions, are introduced. Finally, the prospects and conclusions are highlighted. The MPS method has the potential to solve practical problems.
