Numerical Modelling of Flow-Debris Interaction during Extreme Hydrodynamic Events with DualSPHysics-CHRONO [PDF]
Applied Sciences, 2021 Floods can transport debris of a very wide range of dimensions, from cohesive sediments to large floating debris, such as trees and cars. The latter increases the risk associated with floods by, for example, obstructing the flow or damaging structures ...

Sloshing Simulation of Single-Phase and Two-Phase SPH using DualSPHysics
Kapal, 2020 The sloshing phenomenon is one of the free surface flow that can endanger liquid cargo carriers such as ships. Sloshing is defined as the resonance of fluid inside a tank caused by external oscillation.

DualSPHysics: from fluid dynamics to multiphysics problems [PDF]
Computational Particle Mechanics, 2021 DualSPHysics is a weakly compressible smoothed particle hydrodynamics (SPH) Navier–Stokes solver initially conceived to deal with coastal engineering problems, especially those related to wave impact with coastal structures. Since the first release back in 2011, DualSPHysics has shown to be robust and accurate for simulating extreme wave events along ...

Mass exchange between geophysical flows and beds: Idealised computational modelling using a Herschel-Bulkley rheology [PDF]
E3S Web of Conferences, 2023 A key mechanism by which geophysical flows evolve is mass exchange with the underlying bed, either by entraining material from the bed, or by depositing material.

A portable C++ library for memory and compute abstraction on multi‐core CPUs and GPUs
Concurrency and Computation: Practice and Experience, Volume 35, Issue 25, 15 November 2023., 2023 Abstract We present a C++ library for transparent memory and compute abstraction across CPU and GPU architectures. Our library combines generic data structures like vectors, multi‐dimensional arrays, maps, graphs, and sparse grids with basic generic algorithms like arbitrary‐dimensional convolutions, copying, merging, sorting, prefix sum, reductions ...

Energy Technology, Volume 11, Issue 6, June 2023., 2023 Different flow conditions are simulated to determine the effect of the process parameters and the screw geometry on the shear rate in the extruder. The screw rotational speed has the greatest effect on the shear rate. Moreover, partial filling of the screw also induces different shear profiles due to material flow behavior.

Recent Advances and New Frontiers in Riverine and Coastal Flood Modeling
Reviews of Geophysics, Volume 61, Issue 2, June 2023., 2023 Abstract Over the past decades, the scientific community has made significant efforts to simulate flooding conditions using a variety of complex physically based models. Despite all advances, these models still fall short in accuracy and reliability and are often considered computationally intensive to be fully operational.

Journal of Flood Risk Management, Volume 16, Issue 2, June 2023., 2023 Abstract This study combines laboratory experiments and numerical modelling in a novel manner to assess vehicle stability. Assessing vehicle stability forms the basis of hazard classification criteria, which in turn helps in forming safety guidelines for stream crossings and planning of evacuation routes in times of floods.
