Smoothed Particle Hydrodynamics (SPH) is the most widely established mesh-free method which has been used in several fields as astrophysics, solids mechanics and fluid dynamics. In the particular case of computational fluid dynamics, the model i[...]

The roll motion response of a single degree of freedom (SDOF) structural system to which a rigid rectangular partially filled liquid tank has been attached is considered. The SDOF structural system with the empty tank is first described with a m[...]

An Arbitrary Lagrange Euler (ALE) description of fluid flows is used together with the meshless numerical method Smoothed Particle Hydrodynamics (SPH) to simulate free surface flows. The ALE description leads to an hybrid method that can be clos[...]

Two algorithms of the SPH Lagrangian numerical method, the first weakly compressible, the second truly incompressible, are presented and applied to two free-surface three-dimensional flows. The first (schematic) case consists of a water column c[...]

In this contribution the coupling of the Smoothed Particle Hydrodynamics (SPH) method for fluid dynamics to Finite Elements (FE) for structures is discussed. The accuracy of the SPH method for hydrodynamics will be demonstrated by the case of a [...]

A Smoothed Particle Hydrodynamics (SPH) method for free surface flows has been implemented on a graphical processing unit (GPU) using the Compute Unified Device Architecture (CUDA) developed by Nvidia, resulting in tremendous speed-ups. The enti[...]

The present work introduces a numerical representation of the rheological non Newtonian Bingham model by means of the Smoothed Particle Hydrodynamics (SPH) approach. The model is first re-written using the SPH formalism. Then, it is tested using[...]

It is difficult to study the process of wave propagation from the deep ocean to the nearshore region using a single model due to the presence of multiple scales both in time and in space. Numerical models based on the Boussinesq equations are we[...]

The flip-through phenomenon has been observed in several conditions characterized by a steep wave approaching a vertical wall (Peregrine 2003). One of the cases where this phenomenon has been observed and studied experimentally is the sloshing i[...]

Free surface flows represent a significant problem in computational fluid dynamics (CFD). The difficulties are multiplied when the free surfaces overturn or impact against solid surfaces, especially if air is entrapped in the process. Although m[...]

In the present paper, a Smoothed Particle Hydrodynamics (SPH) modeling of the shallow water equations is presented. The objective of this modeling is to perform flooding simulations involving complex bathymetries of sea bottom and dry land. The [...]

Smoothed Particle Hydrodynamics (SPH) is used to simulate the movement of a caisson breakwater in the surf zone. The open-source code SPHysics is used with a Riemann solver-based formulation. The friction force between the moving caisson and the[...]

The capability of Smoothed Particle Hydrodynamics (SPH) to reproduce a mobile hydraulic jump was investigated.A similar case was used to generate different upstream Froude numbers to obtain several jump shapes. A physical model was then construc[...]
