Numerical simulation of wave interaction with porous structures
TL;DR: In this paper, a more realistic simulation by simultaneous consideration of the porous structure reshaping and fluid flow interactions is presented, where the wave interactions with the porous media together with the breakwater deformation are modeled using a combination of FVM-VOF-DEM numerical methods.

A flexible fully nonlinear potential flow model for wave propagation over the complex topography of the Norwegian coast
TL;DR: In this paper , a potential flow model with a σ-grid for the purpose of coastal wave modeling is presented. But the model is not suitable for the simulation of large-scale engineering scenarios and the applicability of the coastline algorithm is limited.

Numerical simulation of sloshing flow in a 2D rectangular tank with porous baffles
TL;DR: In this paper , the porous media theory is applied to simulate the porous baffles for analyzing the influence of the porous materials on the sloshing flow due to a roll motion, and the effects of the baffle arrangement and excitation frequencies on wave damping performance are analyzed in detail.

Reduction of the wave propagation error of a sigma grid based numerical tank using a vertical spacing based on the constant truncation error
TL;DR: In this article, a new method based on the constant truncation error of the finite difference scheme is presented in order to reduce the uncertainty of the dispersion relation and optimise the choice of the vertical grid distribution.

Numerical simulation of anti-sloshing performance in a 2D rectangular tank with random porous layer
TL;DR: In this paper , the OpenFOAM was extended to solve the interaction between sloshing flow and the random porous structure, and the accuracy of the extension was validated by comparing the numerical results with experimental data.

Efficient Implementation of Weighted ENO Schemes
Guang-Shan Jiang,Chi-Wang Shu +1 more
TL;DR: A new way of measuring the smoothness of a numerical solution is proposed, emulating the idea of minimizing the total variation of the approximation, which results in a fifth-order WENO scheme for the caser= 3, instead of the fourth-order with the original smoothness measurement by Liuet al.

Efficient implementation of essentially non-oscillatory shock-capturing schemes,II
Chi-Wang Shu,Stanley Osher +1 more
TL;DR: Two methods of sharpening contact discontinuities-the subcell resolution idea of Harten and the artificial compression idea of Yang, which those authors originally used in the cell average framework-are applied to the current ENO schemes using numerical fluxes and TVD Runge-Kutta time discretizations.

Numerical solution of the Navier-Stokes equations
TL;DR: In this paper, a finite-difference method for solving the time-dependent Navier-Stokes equations for an incompressible fluid is introduced, which is equally applicable to problems in two and three space dimensions.
