Irregular Wave Validation of a Coupling Methodology for Numerical Modelling of Near and Far Field Effects of Wave Energy Converter Arrays [PDF]
Energies, 2019 Between the Wave Energy Converters (WECs) of a farm, hydrodynamic interactions occur and have an impact on the surrounding wave field, both close to the WECs (“near field„ effects) and at large distances from their location (“far field&#

Validation of Mean Drift Forces Computed with the BEM Code NEMOH [PDF]
, 2017 This report covers a simple investigation of mean drift forces found by use of the boundary element method code NEMOH. The results from NEMOH are compared to analytical results from literature and to numerical values found from the commercial software package WADAM by DNV-GL.The work was conducted under the project "Mooring Solutions for Large Wave ...

Using NEMOH for Modelling Wave Energy Converters: A Comparative Study with WAMIT [PDF]
, 2017 Despite the well-known limitations of linear potential flow theory, hydrodynamic coefficients obtained from boundary element methods (BEM) are commonly used to estimate the hydrodynamic parameters of wave energy converters (WECs).These parameters may then be used to simulate the behavior of WECs in response to incident waves.

Theoretical and numerical aspects of the open source BEM solver NEMOH
, 2015 The aim of this paper is to provide the key theoretical and numerical aspects of the NEMOH software. NEMOH is a numerical solver for computations of first order hydrodynamic coefficients in frequency domain. It is based on linear free surface potential flow theory. It has been developed in Ecole Centrale de Nantes for 30 years.

Experimental investigations on the explosivity of steam-driven eruptions: A case study of Solfatara volcano (Campi Flegrei). [PDF]
J Geophys Res Solid Earth, 2016 Abstract Steam‐driven eruptions, both phreatic and hydrothermal, expel exclusively fragments of non‐juvenile rocks disintegrated by the expansion of water as liquid or gas phase. As their violence is related to the magnitude of the decompression work that can be performed by fluid expansion, these eruptions may occur with variable degrees of ...

A spectral element solution of the two‐dimensional linearized potential flow radiation problem
International Journal for Numerical Methods in Fluids, Volume 95, Issue 3, Page 453-471, March 2023., 2023 In this article, a scalable 2D Galerkin spectral element method solution to the linearized potential flow radiation problem for wave induced forcing of a floating offshore structure is presented. The pseudo‐impulsive formulation of the problem is solved in the time domain using a Gaussian displacement signal tailored to the discrete resolution.

A review of modelling techniques for floating offshore wind turbines
Wind Energy, Volume 25, Issue 5, Page 831-857, May 2022., 2022 Abstract Modelling floating offshore wind turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating platform. Physical testing at scale is faced with the additional challenge of the scaling mismatch between Froude number and Reynolds number due to working in the two fluid ...
