Capabilities and limitations of smoothed particle hydrodynamics for the simulation of two‐phase flow instabilities

PAMM, Volume 24, Issue 4, December 2024.
Abstract Smoothed particle hydrodynamics (SPH) is a mesh‐free, Lagrangian particle‐based method that is able to simulate multiphase flows in an economical manner. However, its ability to capture the flow regimes and regime transitions in two phase (liquid‐gas) internal flows, such as pipe or channel flows is not yet generally established.

A sequential sampling strategy for extreme event statistics in nonlinear dynamical systems

, 2018
We develop a method for the evaluation of extreme event statistics associated with nonlinear dynamical systems, using a small number of samples. From an initial dataset of design points, we formulate a sequential strategy that provides the 'next-best ...

A SPH numerical wave basin for modeling wave-structure interactions [PDF]

, 2016
Based on a parallel SPH-LES model, a three dimensional numerical wave basin is developed to study wave interaction with coastal structures. The OpenMP programming technology combined with an existing MPI program contained in the parallel version of ...

Centrifuge Experiment on Capture Performance of Open‐Type Sabo Dam with Its Numerical Analysis

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Open‐type Sabo dam captures the advantage of solids mitigating the potential energy of fluids, but the disadvantage is that a small amount of debris flow passes through the dam, the reason for this comes from the grid size of the dam, the inclination angle of the dam, the stone size among the debris flow, etc.

A New Experimental Study and SPH Comparison for the Sequential Dam-Break Problem

Journal of Marine Science and Engineering, 2020
The floods following the event of a dam collapse can have a significant impact on the downstream environment and ecology. Due to the limited number of real-case data for dam-break floods, laboratory experiments and numerical models are used to understand

SPH simulation of floating structures with moorings

, 2019
The open-source code DualSPHysics is applied to simulate the interaction of sea waves with floating offshore structures, which are typically moored to the seabed, such as vessels, boats, floating breakwaters and wave energy converters (WECs). The goal is

WALOWA (wave loads on walls) : large-scale experiments in the delta flume [PDF]

, 2017
Overtopping wave loads on vertical structures on top of a dike have been investigated in several small scale experiments in the past. A large-scale validation for a mild foreshore situation is still missing.

An Inter-Model Comparison for Wave Interactions with Sea Dikes on Shallow Foreshores

Journal of Marine Science and Engineering, 2020
Three open source wave models are applied in 2DV to reproduce a large-scale wave flume experiment of bichromatic wave transformations over a steep-sloped dike with a mildly-sloped and very shallow foreshore: (i) the Reynolds-averaged Navier–Stokes ...
