Multiphase smoothed-particle hydrodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 We adapt the smoothed-particle hydrodynamics (SPH) technique to allow a multiphase fluid in which SPH particles of widely differing density may be freely intermixed.

Smoothed Particle Hydrodynamics [PDF]
, 2005 Smoothed Particle Hydrodynamics (SPH) is a unique numerical method widely used for astrophysical problems since it involves no spatial grid. Rather, fluid quantities are carried by a set of Lagrangian `particles' which move with the flow, meaning that complicated dynamics and asymmetric phenomena are treated with ease.

Efficient smoothed particle radiation hydrodynamics II: Radiation hydrodynamics [PDF]
Journal of Computational Physics, 2021 The radiation hydrodynamics equations for smoothed particle hydrodynamics are derived by operator splitting the radiation and hydrodynamics terms, including necessary terms for material motion, and discretizing each of the sets of equations separately in time and space.

A global analysis of a coupled violent vertical sloshing problem using an SPH methodology
Engineering Applications of Computational Fluid Mechanics, 2021 A dynamical system involving the decaying test of a partially filled liquid tank is analyzed in the present paper. This analysis is relevant for the design of aircraft fuel tanks, where the wings' structural dynamics are influenced by the complexity and ...

Thin-film smoothed particle hydrodynamics fluid [PDF]
ACM Transactions on Graphics, 2021 We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. We build our dynamics model from the surface tension driven Navier-Stokes equation with the dimensionality reduced using the asymptotic lubrication theory and customize a set of differential operators ...

Moving least-squares corrections for smoothed particle hydrodynamics
Annals of Geophysics, 2011 First-order moving least-squares are typically used in conjunction with smoothed particle hydrodynamics in the form of post-processing filters for density fields, to smooth out noise that develops in most applications of smoothed particle hydrodynamics ...

Sparse Inpainting with Smoothed Particle Hydrodynamics [PDF]
SIAM Journal on Imaging Sciences, 2021 Digital image inpainting refers to techniques used to reconstruct a damaged or incomplete image by exploiting available image information. The main goal of this work is to perform the image inpainting process from a set of sparsely distributed image samples with the Smoothed Particle Hydrodynamics (SPH) technique.
