Particle methods in ocean and coastal engineering
TL;DR: In this paper, a review of particle methods in hydrodynamics-related problems in ocean and coastal engineering is presented, where the problems are placed into three categories according to their physical characteristics, namely, wave hydrodynamic and corresponding mass transport, wave-structure interaction, and wave-current-sediment interaction.

Theoretical method for generating solitary waves using plunger-type wavemakers and its Smoothed Particle Hydrodynamics validation
TL;DR: In this paper, a theoretical method for the precise descent of an arbitrary-geometry plunger is derived and constraints on the produced wave height are given, taking wedge-shaped, box-shaped and cylinder-shaped plungers as examples.

Influences of free surface jump conditions and different k−ω SST turbulence models on breaking wave modelling
TL;DR: In this article, a two-phase flow Computational Fluid Dynamics (CFD) model is employed for both spilling and plunging breaking wave simulations, and a numerical wave tank is built to evaluate the performance of two different free surface modelling approaches (i.e., continuous free surface conditions and free surface jump conditions) and three k − ω SST turbulence models (a newly proposed model)).

On hydrodynamic characteristics of transient harbor resonance excited by double solitary waves
TL;DR: In this article, the effects of incident wave height, relative separation distance and bottom profile on hydrodynamic characteristics related to the transient oscillations are mainly investigated, including the evolution of the maximum free-surface elevation, the maximum runup, the wave energy distribution and the total wave energy inside the harbor.

Multi-resolution technique integrated with smoothed particle element method (SPEM) for modeling fluid-structure interaction problems with free surfaces
Ting Long,Z.L. Zhang,Moubin Liu +2 more
TL;DR: A novel approach is effective in modeling various incompressible flow problems involving FSIs and can significantly reduce the computational cost relative to the original version with a constant resolution by introducing a multi-resolution technique to the SPEM and developing an effective approach to treat multi- resolution element-particle interfaces.

General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.
