Numerical Simulation of the Large‐Scale Huangtian (China) Landslide‐Generated Impulse Waves by a GPU‐Accelerated Three‐Dimensional Soil‒Water Coupled SPH Model

Water Resources Research, 2023
This work presents an improved soil‒water coupling model to simulate landslide‐generated impulse waves (LGIWs) in a unified smoothed particle hydrodynamics (SPH) framework, where both water flow and landslide motions are modeled by SPH using an interface

Composite modelling of the effect of the water body geometry on landslide-tsunamis [PDF]

, 2015
Subaerial landslide-tsunamis (impulse waves) are generated by mass movements such as landslides, rock falls or glacier calving interacting with a water body. Preliminary landslide-tsunami hazard assessment is commonly based on empirical equations derived

Numerical Model of Wave Transmission on Curtain-Wall Pile Breakwater with DualSPHysics

Jurnal Teknik Pengairan
One of the problems often encountered in coastal areas is changes in coastal morphology caused by wave propagation. Curtain Wall-Pile Breakwater (CPB) is a practical alternative to dampen waves heading towards the shore.

Validation of DualSPHysics for viscous Newtonian flow fronts

, 2022
Viscous, surging flow fronts are encountered in many applications in geophysics such as debris-, mud-and lavaflows. Few applications of the SPH method for low Reynolds, viscous flows have been rigorously validated against experimental data. In this paper, the validation of the DualSPHysics software against well documented experimental data of a laminar

Numerical simulation of water wave propagation using DualSPHysics

IOP Conference Series: Earth and Environmental Science
Abstract In this study, the study of water waves was carried out using one of major the mesh-free CFD i.e. Smoothed Particle Hydrodynamics (SPH). DualSPHysics ver 5.0 which is an open-source SPH solver based on Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) was used to reproduce three dimension of water waves in large and ...
