Investigation of physical issues of the initial conditions of free water surface due to underwater disturbances on the basis of SPH numerical simulation of the phenomenon

Journal of Theoretical and Applied Physics, 2019
The current paper discusses the physical impacts of the various initial boundary conditions of the free surface of a waterbody on the initiation and propagation characteristics of water waves due to the underwater perturbations.

Performance Assessment of a Planing Hull Using the Smoothed Particle Hydrodynamics Method

Journal of Marine Science and Engineering, 2021
Computational Fluid Dynamics simulations of planing hulls are generally considered less reliable than simulations of displacement hulls. This is due to the flow complexity around planing hulls, especially in the bow region, where the sprays are formed ...

Mathematical modelling of wave forces on cylinders group using DualSPHysics [PDF]

AIP Conference Proceedings, 2016
The design of the coastal structure or offshore structure must take into account the hydrodynamic force of water waves to assure the structure stability. In many cases, offshore structures are supported by a group of cylinders piles. The distance between the cylinders and their layout may affect the force on the cylinder which can be not calculated ...

Open-source software for modelling of free surface flows

Труды Института системного программирования РАН, 2018
Problems of free-surface flow of viscous incompressible fluid are very useful in different practical cases. There are many specifies and limitations in these problems which are critically important for correct solving.

Non-linear wave generation and absorption using open boundaries within DualSPHysics [PDF]

Computer Physics Communications, 2019
The present work introduces the implementation of wave generation and wave absorption of nonlinear, long-crested regular and irregular waves in the WCSPH-based (Weakly Compressible Smoothed Particle Hydrodynamics) DualSPHysics solver. Open boundaries are applied here for both wave generation and absorption.

DualSPHysics: from fluid dynamics to multiphysics problems

, 2022
[Abstract:] 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 ...

Smoothed Particle Hydrodynamics Simulations of Wave Run-Up over Hexaloc Armour on Rubble-Mound Breakwaters [PDF]

BIO Web of Conferences
Indonesian beaches are increasingly vulnerable to abrasion and erosion, requiring reliable protection such as breakwaters. Since crest freeboard determines the level of safety, wave run-up predictions must be accurate.
