Sloshing Simulation of Single-Phase and Two-Phase SPH using DualSPHysics

Kapal, 2020
The sloshing phenomenon is one of the free surface flow that can endanger liquid cargo carriers such as ships. Sloshing is defined as the resonance of fluid inside a tank caused by external oscillation.

Boosting the accuracy of SPH techniques: Newtonian and special-relativistic tests [PDF]

, 2015
We study the impact of different discretization choices on the accuracy of SPH and we explore them in a large number of Newtonian and special-relativistic benchmark tests.

Smoothed particle hydrodynamics with adaptive spatial resolution (SPH-ASR) for free surface flows [PDF]

Journal of Computational Physics, 2020
A numerical method based on smoothed particle hydrodynamics with adaptive spatial resolution (SPH-ASR) was developed for simulating free surface flows. This method can reduce the computational demands while maintaining the numerical accuracy.

Smoothed Particle Hydrodynamics and Magnetohydrodynamics [PDF]

, 2010
This paper presents an overview and introduction to Smoothed Particle Hydrodynamics and Magnetohydrodynamics in theory and in practice. Firstly, we give a basic grounding in the fundamentals of SPH, showing how the equations of motion and energy can be ...

Detailed study on the extension of the δ-SPH model to multi-phase flow

, 2020
In the present work the multi-phase SPH model presented in Grenier et al. (2009) is considered and extended through the inclusion of a diffusive term in the continuity equation. The latter based on the δ -SPH model of Antuono et al.
