“…Gotoh and Sakai 2006). The pioneering work related to multiphase flow simulations by projection-based particle methods corresponds to that by Gotoh and Fredsøe (2000) who developed a solid-liquid twophase MPS method. A number of interesting ocean or coastal engineering applications have been studied by solid-liquid MPS methods as illustrated by Gotoh and Sakai (2006).…”

“…By solving the Poisson Pressure Equation (PPE), the MPS method is suitable for the simulations of fully incompressible flow. The first MPS multiphase method is developed by Gotoh and Fredsøe [2] for solid-liquid twophase flows. Liu et al [3] proposed a hybrid MPS-FVM method for the viscous, incompressible, multiphase flows, in which the heavier fluid is represented by moving particles while the lighter fluid is defined on the mesh.…”

The Rayleigh-Taylor instability problem is one of the classic hydrodynamic instability cases in natural scenarios and industrial applications. For the numerical simulation of the Rayleigh-Taylor instability problem, this paper presents a multiphase method based on the moving particle semi-implicit (MPS) method. Herein, the incompressibility of the fluids is satisfied by solving a Poisson Pressure Equation and the pressure fluctuation is suppressed. A single set of equations is utilized for fluids with different densities, making the method relatively simple. To deal with the mathematical discontinuity of density in the two-phase interface, a transitional region is introduced into this method. For particles in the transitional region, a density smoothing scheme is applied to improve the numerical stability. The simulation results show that the present MPS multiphase method is capable of capturing the evolutionary features of the Rayleigh-Taylor instability, even in the later stage when the two-phase interface is quite distorted. The unphysical penetration in the interface is limited, proving the stability and accuracy of the proposed method.

“…Based on MPS, other models are invented; for instance, Gotoh and Fredso [20] proposed a multiphase flow model for solid-liquid simulation, Ikari et al [21] proposed a gasliquid two-phase flow model, and Koshizuka model is modified to fit the phenomena treated in hydraulic engineering. Feng and Huang [22] presented a 3D MPS method to simulate the supersonic atomization process, and the stability enhancement is discussed in detail.…”

Modified 3D Moving Particle Semi-Implicit (MPS) method is used to complete the numerical simulation of the fluid sloshing in LNG tank under multidegree excitation motion, which is compared with the results of experiments and 2D calculations obtained by other scholars to verify the reliability. The cubic spline kernel functions used in Smoothed Particle Hydrodynamics (SPH) method are adopted to reduce the deviation caused by consecutive two times weighted average calculations; the boundary conditions and the determination of free surface particles are modified to improve the computational stability and accuracy of 3D calculation. The tank is under forced multidegree excitation motion to simulate the real conditions of LNG ships, the pressures and the free surfaces at different times are given to verify the accuracy of 3D simulation, and the free surface and the splashed particles can be simulated more exactly.
