Journal ArticleDOI
Numerical simulation of interfacial flows by smoothed particle hydrodynamics
TL;DR: In this article, an implementation of the smoothed particle hydrodynamics (SPH) method is presented to treat two-dimensional interfacial flows, that is, flow fields with different fluids separated by sharp interfaces.
Journal ArticleDOI
δ-SPH model for simulating violent impact flows
Salvatore Marrone,Matteo Antuono,Andrea Colagrossi,Giuseppina Colicchio,D. Le Touzé,Giorgio Graziani +5 more
TL;DR: In this article, a smoothed particle hydrodynamics model with numerical diffusive terms is used to analyze violent water flows and boundary conditions on solid surfaces of arbitrary shape are enforced with a new technique based on fixed ghost particles.
Journal ArticleDOI
A simple procedure to improve the pressure evaluation in hydrodynamic context using the SPH
Diego Molteni,Andrea Colagrossi +1 more
TL;DR: A simple procedure is proposed to improve the computation of the pressure distribution in the dynamics of liquids, based on the use of a density diffusion term in the equation for the mass conservation.
Journal ArticleDOI
Free-surface flows solved by means of SPH schemes with numerical diffusive terms
TL;DR: A novel system of equations has been defined which contains diffusive terms in both the continuity and energy equations and, at the leading order, coincides with a standard weakly-compressible SPH scheme with artificial viscosity, showing to be robust, efficient and accurate.
Journal ArticleDOI
An Hamiltonian interface SPH formulation for multi-fluid and free surface flows
TL;DR: A new SPH model for simulating interface and free surface flows is presented, an extension of the one discussed in Colagrossi and Landrini (2003) and related to the one proposed by Hu and Adams (2006) to study multi-fluid flows.
