Simulation of Polymer Flow Using Smoothed Particle Hydrodynamics Method [PDF]

, 2013
Reactive rotational molding (RRM) is a process to manufacture hollow plastic articles. Comparing to rotational molding of thermoplastics, it decreases the process cycle time due to the reactivity of the system.

Conservative, special-relativistic smoothed particle hydrodynamics

, 2010
We present and test a new, special-relativistic formulation of Smoothed Particle Hydrodynamics (SPH). Our approach benefits from several improvements with respect to earlier relativistic SPH formulations.

Smoothed Particle Hydrodynamics in Astrophysics [PDF]

Annual Review of Astronomy and Astrophysics, 2010
This review discusses smoothed particle hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formulation of hydrodynamics that has excellent conservation properties and can be coupled to self-gravity with high accuracy.

A discretized integral hydrodynamics [PDF]

, 1997
Using an interpolant form for the gradient of a function of position, we write an integral version of the conservation equations for a fluid. In the appropriate limit, these become the usual conservation laws of mass, momentum and energy. We also discuss

Smoothed particle hydrodynamics

, 2004
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.

A derivation of the entropy-based relativistic smoothed particle hydrodynamics by variational principle

, 2017
In this work, a second order smoothed particle hydrodynamics is derived for the study of relativistic heavy ion collisions. The hydrodynamical equation of motion is formulated in terms of the variational principle.

Embedding Lagrangian Sink Particles in Eulerian Grids [PDF]

, 2003
We introduce a new computational method for embedding Lagrangian sink particles into an Eulerian calculation. Simulations of gravitational collapse or accretion generally produce regions whose density greatly exceeds the mean density in the simulation ...

rpSPH: a novel Smoothed Particle Hydrodynamics Algorithm

, 2010
We suggest a novel discretisation of the momentum equation for Smoothed Particle Hydrodynamics (SPH) and show that it significantly improves the accuracy of the obtained solutions.
