An accurate SPH Volume Adaptive Scheme for modeling strongly-compressible multiphase flows. Part 2: Extension of the scheme to cylindrical coordinates and simulations of 3D axisymmetric problems with experimental validations

Journal of Computational Physics, 2021
The present work is dedicated to extending the strongly-compressible multiphase SPH Volume Adaptive Scheme (see [22] ) from Cartesian to cylindrical polar coordinates for addressing axisymmetric problems.

Ultrarelativistic SPH

Journal of Computational Physics, 1997
The equations of motion of an ultrarelativistic gas are solved using the particle method SPH. The algorithm is based on a form of SPH which integrates the specific energy equation instead of the thermal energy equation and determines the dissipative terms along the lines of Riemann solvers.

A consistent approach to particle shifting in the δ-Plus-SPH model

Computer Methods in Applied Mechanics and Engineering, 2019
In the present work a consistent inclusion of a particle shifting technique (PST) in the weakly compressible Smoothed Particle Hydrodynamic (SPH) models is discussed.

Numerical analysis of dynamic compaction using FEM-SPH coupling method

, 2021
This paper presents the FEM-SPH coupling method for the analysis of large deformation problems caused by dynamic compaction (DC). A 3D FEM-SPH coupling model was established in LS-DYNA to simulate the dynamic compaction process.

An enhanced ISPH-SPH coupled method for simulation of incompressible fluid-elastic structure interactions

Computer Physics Communications, 2018
An enhanced fully-Lagrangian meshfree computational method is developed for simulating incompressible fluid–elastic structure interactions. The developed method corresponds to a SPH (Smoothed Particle Hydrodynamics)-based coupled FSI (Fluid–Structure ...
