Simulation of multiphase flows characterized by high density ratios is targeted by using a refined particle method. The proposed method is founded on Moving Particle Semi-implicit (MPS) method which is a projection-based particle method.

On a Robustness of The Random Particle Method
Monte Carlo Methods and Applications, 1996Summary: We are concerned with the robustness of the so-called random particle methods that have been recognized as efficient tool for the numerical analysis of nonlinear diffusions. Among these, we take the random gradient method due to \textit{E. G. Puckett} [Math. Comput. 52, No.

Coupled finite particle method for simulations of wave and structure interaction
Coastal Engineering, 2018A coupled finite particle method (FPM) is proposed to model wave-structure interaction. The coupled FPM combines the advantages of FPM, smoothed particle hydrodynamics (SPH), δ-SPH model and particle shifting technology (PST).

International Journal for Numerical Methods in Fluids, 2005
AbstractThree, very different particle methods, PIC, SPH and vortex‐blob methods, are compared. Results on consistency and stability are collected. A PIC instability, its properties, and its resolution by stability in the energy norm is discussed at some length.

Radial basis reproducing kernel particle method for piezoelectric materials
Engineering analysis with boundary elements, 2017To reduce the negative effect of different kernel functions on calculating accuracy, the radial basis function (RBF) is introduced into the reproducing kernel particle method (RKPM), and the radial basis reproducing kernel particle method (RRKPM) is ...

A method for recognizing particles in overlapped particle images
Pattern Recognition Letters, 2000This paper describes a new method to divide a planar curve into circular arcs in order to recognize the overlapped particles in an image. The segmentation is based on a new breakpoint detection method. An area correlation coefficient for two arcs is introduced to identify and cluster the arcs belonging to the same circle.

The affine particle-in-cell method
ACM Transactions on Graphics, 2015Hybrid Lagrangian/Eulerian simulation is commonplace in computer graphics for fluids and other materials undergoing large deformation. In these methods, particles are used to resolve transport and topological change, while a background Eulerian grid is used for computing mechanical forces and collision responses.

A Lagrangian Particle‐Wavelet Method
Multiscale Modeling & Simulation, 2006This paper presents a novel, multiresolution Lagrangian particle method with enhanced, wavelet‐based adaptivity. The method is formulated for transport problems and combines the efficiency of wavelet collocation with the inherent numerical stability of particle methods.
