Smoothed particle hydrodynamics (SPH) for free-surface flows: past, present and future

Journal of Hydraulic Research, 2016
This paper assesses some recent trends in the novel numerical meshless method smoothed particle hydrodynamics, with particular focus on its potential use in modelling free-surface flows. Due to its Lagrangian nature, smoothed particle hydrodynamics (SPH) appears to be effective in solving diverse fluid-dynamic problems with highly nonlinear deformation

Smoothed particle hydrodynamics (SPH) modeling of shot peening process

Journal of Computational Methods in Sciences and Engineering, 2017
Shot peening is a cold working process used mainly to improve the fatigue life of metallic components. The complexity of the process makes it difficult and costly to evaluate the mechanism through experiment. Therefore, the purpose of this study is to provide an numerical model for simulating this process.

Modeling Aerodynamic Problems Using Smoothed Particle Hydrodynamics (SPH)

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">Smoothed Particle Hydrodynamics (SPH) is a numerical method that solves the Lagrangian, conservative equations of mass, momentum, and energy without using a computational grid. In the past, SPH has been used to solve problems of astrophysics, hypervelocity collisions, and explosions.

Smoothed particle hydrodynamics (SPH) for modeling fluid-structure interactions

Science China Physics, Mechanics & Astronomy, 2019
Fluid-structure interaction (FSI) is a class of mechanics-related problems with mutual dependence between the fluid and structure parts and it is observable nearly everywhere, in natural phenomena to many engineering systems. The primary challenges in developing numerical models with conventional grid-based methods are the inherent nonlinearity and ...

Smooth particle hydrodynamics (SPH) modelling of laser cutting

ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008
One of the major obstacles in the simulation of laser cutting is the wide span of length scales and the high velocities encountered. Additionally the melt breaks up into a fine spray or shower of droplets when exiting the kerf. Hence the scope for modeling this process with traditional finite volume or finite element methods is limited.

Smooth Particle Hydrodynamics (SPH) for Simulating 2D Elastodynamics Problems

Applied Mechanics and Materials, 2016
SPH is a Lagrangian based computational method that can be used for solving fluids and solid mechanics problems. In this work, SPH is utilized to solve the two dimensional Navier’s equation for linear elastodynamics problems. The SPH technique computes the discrete particle properties using a smoothing distribution function, which takes into account ...

Efficient Implementation of Smoothed Particle Hydrodynamics (SPH) with Plane Sweep Algorithm

Communications in Computational Physics, 2016
AbstractNeighbour search (NS) is the core of any implementations of smoothed particle hydrodynamics (SPH). In this paper,we present an efficientneighbour search method based on the plane sweep (PW) algorithm withNbeing the number of SPH particles. The resulting method, dubbed the PWNS method, is totally independent of grids (i.e., purely meshfree) and ...

Droplet Impact: A GPU Based Smoothed Particle Hydrodynamics (SPH) Approach

Volume 1: Symposia, Parts A and B, 2012
A parallel GPU compatible Lagrangian mesh free particle solver for multiphase fluid flow based on Smoothed Particle Hydrodynamics (SPH) scheme is developed and used to capture the interface evolution during droplet impact. To solve Navier-Stokes equations, the computational domain is discretized using fluid particles.
