Collisions of planetesimals and formation of planets
, 2015 We present preliminary results of terrestrial planet formation using on the one hand classical numerical integration of hundreds of small bodies on CPUs and on the other hand -- for comparison reasons -- the results of our GPU code with thousands of ...

Frontiers in Environmental Science, 2022 The Bingham model can effectively describe the flow behavior of viscoplastic fluid. It is important to study the flow characteristics of Bingham fluid to understand the dynamic mechanism of viscous debris flow.

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.

SPH Simulation of single grain action in grinding
MATEC Web of Conferences, 2017 The paper presents a study of chip formation in single grain grinding using a convenient FEM formulation, the Smooth Particle Hydrodynamics (SPH) method. The chip formation process was geometrically idealized.

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.

Recent progress in anisotropic hydrodynamics [PDF]
, 2016 The quark-gluon plasma created in a relativistic heavy-ion collisions possesses a sizable pressure anisotropy in the local rest frame at very early times after the initial nuclear impact and this anisotropy only slowly relaxes as the system evolves. In a

Ionizing radiation in smoothed particle hydrodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 A new method for the inclusion of ionizing radiation from uniform radiation fields into 3D Smoothed Particle Hydrodynamics (SPHI) simulations is presented. We calculate the optical depth for the Lyman continuum radiation from the source towards the SPHI particles by ray-tracing integration.

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.
