SPH Simulation of Interior and Exterior Flow Field Characteristics of Porous Media [PDF]
, 2020 At the present time, one of the most relevant challenges in marine and ocean engineering and practice is the development of a mathematical modeling that can accurately replicate the interaction of water waves with porous coastal structures. Over the last

Moving least-squares corrections for smoothed particle hydrodynamics
Annals of Geophysics, 2011 First-order moving least-squares are typically used in conjunction with smoothed particle hydrodynamics in the form of post-processing filters for density fields, to smooth out noise that develops in most applications of smoothed particle hydrodynamics ...

Thin-film smoothed particle hydrodynamics fluid [PDF]
ACM Transactions on Graphics, 2021 We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. We build our dynamics model from the surface tension driven Navier-Stokes equation with the dimensionality reduced using the asymptotic lubrication theory and customize a set of differential operators ...

Smoothed particle hydrodynamics with smoothed pseudo-density [PDF]
Publications of the Astronomical Society of Japan, 2015 Abstract In this paper, we present a new formulation of smoothed particle hydrodynamics (SPH), which, unlike the standard SPH (SSPH), is well behaved at the contact discontinuity. The SSPH scheme cannot handle discontinuities in density (e.g., the contact discontinuity and the free surface), because it requires that the density of fluid ...

Sparse Inpainting with Smoothed Particle Hydrodynamics [PDF]
SIAM Journal on Imaging Sciences, 2021 Digital image inpainting refers to techniques used to reconstruct a damaged or incomplete image by exploiting available image information. The main goal of this work is to perform the image inpainting process from a set of sparsely distributed image samples with the Smoothed Particle Hydrodynamics (SPH) technique.
