Abstract This paper presents a brief review of grand challenges Smoothed Particle Hydrodynamics (SPH) method. As meshless method, SPH can simulate large range applications from astrophysics to free-surface flows, complex mixing problems in industry and has had notable successes. young computational the method still requires development address important elements which prevent more widespread use. effort been led by members rEsearch engineeRing International Community (SPHERIC) who have...
In the present work, an in-depth analysis of theoretical structure smoothed-particle hydrodynamics (hereinafter SPH) is provided for inviscid, weakly compressible, and barotropic flow in presence a free surface. The role surface SPH scheme indeed little addressed literature. analysis, general continuous formulation method considered. A detailed description free-surface influence on smoothed differential operators supplied. New existing forms are analyzed detail, terms convergence...
The theoretical formulation of the smoothed particle hydrodynamics (SPH) method deserves great care because some inconsistencies occurring when considering free-surface inviscid flows. Actually, in SPH formulations one usually assumes that (i) surface integral terms on boundary interpolation kernel support are neglected, (ii) conditions implicitly verified. These assumptions studied detail present work for Newtonian viscous flow. consistency classical weakly compressible is investigated. In...
During the process of wave slamming on a structure with sharp corners, receding after impingement can induce strong negative pressure (relative to atmospheric pressure) at bottom structure, which is called suction effect. From practical point view, force induced by pressure, coinciding gravity force, pulls down and hence increases risk structural damage. In this work, smoothed particle hydrodynamics (SPH) method, more specifically δ+SPH model, adopted simulate freak fixed platform...
Abstract. In the present paper we propose a method for studying extreme-wave appearance based on Higher-Order Spectral (HOS) technique proposed by West et al. (1987) and Dommermuth Yue (1987). The enhanced HOS model use is presented validated test cases. Investigations of freak-wave events appearing within long-time evolutions 2-D 3-D wavefields in open seas are then realized, results discussed. Such obtained our periodic-domain using different kinds configurations: either i) impose an...
SUMMARY In this paper, an in‐depth study of SPH method, in its original weakly compressible version, is achieved on dedicated 2D and 3D free‐surface flow test cases. These rather critical prototype problems shall constitute suitable cases to get through when building a model. The present work aims at investigating various numerical aspects often little mentioned literature. particular, great care paid the dynamic part solution, which local hydrodynamic load prediction. role errors...
