Numerical modelling of tsunami bore impact on low-rise residential buildings using SPH [PDF]

MATEC Web of Conferences, 2019
The resilience of buildings subject to tsunami bore impact can be improved by reducing tsunami-induced lateral hydrodynamic pressure by allowing part of the tsunami bore to pass through the buildings via openings and break-away walls.

Flow Kinematics in Three‐Dimensional Porous Media of Varying Pore Size Distribution Using Smoothed Particle Hydrodynamics

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract The effect of pore size distribution on the flow kinematics and transport properties within a three‐dimensional porous medium is investigated through numerical simulations using the Smoothed Particle Hydrodynamics (SPH) method. The method is first validated for a model porous medium within a monodisperse random spherical packing, for which the

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics

International Journal for Numerical Methods in Fluids, Volume 97, Issue 9, Page 1248-1279, September 2025.
This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.

Theoretical and numerical investigation of wave attenuation on vegetated seabeds

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
Vegetation has a strong impact on ecosystems and habitats, affecting the transport and diffusion processes of nutrients and sediments. The present research aims to analyse, from a theoretical and numerical point of view, the attenuation of a wave propagating through an array of rigid submerged cylindrical stems on a horizontal bottom.

Experimental Research on Shallow‐Water Sloshing Resonant Frequencies in Rectangular Tanks Under Lateral Regular and Irregular Excitations

Shock and Vibration, Volume 2025, Issue 1, 2025.
Sloshing‐induced loads in the shallow‐water tanks have an important impact on ship stability and structural safety. This study experimentally investigates the kinematic characteristics of shallow‐water sloshing motions in rectangular tanks under regular and irregular lateral excitations.

Coupling an SPH-based solver with an FEA structural solver to simulate free surface flows interacting with flexible structures [PDF]

, 2023
This work proposes a two-way coupling between a Smoothed Particle Hydrodynamics (SPH) model-based named DualSPHysics and a Finite Element Analysis (FEA) method to solve fluid–structure interaction (FSI).
