Analysis of Temperature and Plastic Flow during Friction Stir Spot Welding Using Particle Method

open access: yesJournal of Thermal Science and Technology, 2009
Friction stir spot welding (FSSW) is a new metal-joining process, and a numerical simulation code to calculate optimal welding conditions is desired. In this paper, we analyzed temperature distribution and plastic deformation flow during the FSSW process

Particle dynamic trajectory measurement method based on asynchronous delay method

open access: yesDianzi Jishu Yingyong, 2020
In order to obtain the details of the moon dust particles dynamic trajectory on the moon, and reduce the damage of the moon dust particles to the aircraft and astronauts, a particle dynamic trajectory measurement method was proposed, based on the ...

Measuring every particle's size from three-dimensional imaging experiments

open access: yes, 2012
Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle, the consequences of this polydispersity are unknown as it is difficult to

Yet another fast multipole method without multipoles --- Pseudo-particle multipole method

open access: yes, 1998
In this paper we describe a new approach to implement the O(N) fast multipole method and $O(N\log N)$ tree method, which uses pseudoparticles to express the potential field.

A polynomial particle-in-cell method [PDF]

open access: yesACM Transactions on Graphics, 2017
Recently the Affine Particle-In-Cell (APIC) Method was proposed by Jiang et al.[2015; 2017b] to improve the accuracy of the transfers in Particle-In-Cell (PIC) [Harlow 1964] techniques by augmenting each particle with a locally affine, rather than locally constant description of the velocity.

Numerical Study of a Particle Method for Gradient Flows [PDF]

open access: yes, 2015
We study the numerical behaviour of a particle method for gradient flows involving linear and nonlinear diffusion. This method relies on the discretisation of the energy via non-overlapping balls centred at the particles.

Methods for ray-tracing thermal modelling of Saturn's main rings

open access: yesMethodsX, 2021
The thermal emission and temperatures of the main rings of Saturn depend on the energy the ring particles absorb, reflect and scatter and/or on their Bond albedo, emissivity, thermal inertia, rotation rate and porosity.

Particle methods: An introduction with applications [PDF]

open access: yesESAIM: Proceedings, 2014
Summary: Interacting particle methods are increasingly used to sample from complex high-dimensional distributions. They have found a wide range of applications in applied probability, Bayesian statistics and information engineering. Understanding rigorously these new Monte Carlo simulation tools leads to fascinating mathematics related to Feynman-Kac ...

Availability of multi-particle collision dynamics method for magnetic particle suspensions

open access: yesNihon Kikai Gakkai ronbunshu, 2018
In order to apply the multi-particle collision dynamics (MPCD) method to a magnetic particle suspension, we have elucidated the dependence of the translational and rotational Brownian motion of magnetic particles on the MPCD parameters that characterize ...
