Proceedings in Applied Mathematics and Mechanics, 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 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

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.

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 ...

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
