Moving-Particle Semi-Implicit Method for Fragmentation of Incompressible Fluid
Nuclear Science and Engineering, 1996AbstractA moving-particle semi-implicit (MPS) method for simulating fragmentation of incompressible fluids is presented. The motion of each particle is calculated through interactions with neighboring particles covered with the kernel function. Deterministic particle interaction models representing gradient, Laplacian, and free surfaces are proposed ...

Numerical Simulation of Unidirectional Stratified Flow by Moving Particle Semi Implicit Method
Communications in Computational Physics, 2014AbstractNumerical simulation of stratified flow of two fluids between two infinite parallel plates using the Moving Particle Semi-implicit (MPS) method is presented. The developing process from entrance to fully development flow is captured. In the simulation, the computational domain is represented by various types of particles.

A general form of Laplacian model is derived for the numerical framework of Moving Particle Semi-implicit (MPS) method. The existing proposals of MPS Laplacian model available in the open literature can indeed be reproduced from this general Laplacian model.

Moving Particle Semi-Implicit Method for Control of Swarm Robotic Systems
2019 IEEE 11th International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment, and Management ( HNICEM ), 2019The advancements of Multiple Robot Systems (MRS) have shown advantages over single robot systems. Generally, the motivations for the development of MRS are task flexibility, time efficiency, and single-point failure resiliency. The challenge in MRS, however, is the control and coordination of all the members in the system when performing tasks.

A Performance Study of Moving Particle Semi-Implicit Method for Incompressible Fluid Flow on GPU
International Journal of Distributed Systems and Technologies, 2020The aim of moving particle semi-implicit (MPS) is to simulate the incompressible flow of fluids in free surface. MPS, when implemented, consumes a lot of time and thus, needs a very powerful computing system. Instead of using parallel computing system, the performance level of the MPS model can be improved by using graphics processing units (GPUs). The

A stable moving-particle semi-implicit method for free surface flows
Fluid Dynamics Research, 2006In this paper, a mesh-less numerical approach is utilized to solve Euler's equation that is the governing equation of the irrotational flow of ideal fluids. A fractional step method of discritization is applied which consists to split each time step in two steps.

Enhancement of Pressure and Curvature Calculation for the Moving Particle Semi-Implicit Method
Volume 8: Computational Fluid Dynamics (CFD); Nuclear Education and Public Acceptance, 2018This paper aims at illustrating a number of methods for stabilizing pressure solution and improving surface curvature calculation for the simulation using the moving particle semi-implicit (MPS) method. The unphysical numerical oscillation of pressure originated from the original MPS method can be suppressed by adjusting the collision coefficient in ...

Modified moving particle semi-implicit meshless method for incompressible fluids
Journal of Thermal Science, 2004A modified moving particle semi-implicit method (MPS) is presented for incompressible fluids. Modification is on the removal of imaginary nodes to enforce the boundary conditions. Comparison with the original imaginary-node scheme has proved the validity of the proposed method.

An Improved Moving Particle Semi-Implicit Method for Free Surface Flows
Applied Mechanics and Materials, 2014The objective of this study is to make some improvements to the original Moving Particle Semi-implicit method (MPS) for free surface flows. Compared to traditional mesh methods, MPS is feasible to simulate surface flows with large deformation, however, during the simulation; the pressure oscillation is quite violent, duo to misjudgment of surface ...

Smooth particle approach for surface tension calculation in moving particle semi-implicit method
Fluid Dynamics Research, 2010We present here an algorithm to solve three-dimensional multi-phase flow problems based on the moving particle semi-implicit (MPS) method. The method is fully Lagrangian and can treat flows with large deformations of the interface such as encountered in the break-up and coalescence of drops. The mean curvature and normal vector of the interface, needed
