Crest modifications to reduce wave overtopping of non-breaking waves over a smooth dike slope Ghent University
An experimental study on scale effects in wave reflection of low-reflective quay walls with internal rubble mound for regular and random waves Ghent University
Wake effect assessment in long- and short-crested seas of heaving-point absorber and oscillating wave surge WEC arrays Ghent University
In the recent years, the potential impact of wave energy converter (WEC) arrays on the surrounding wave field has been studied using both phase-averaging and phase-resolving wave propagation models. Obtaining understanding of this impact is important because it may affect other users in the sea or on the coastline. However, in these models a parametrization of the WEC power absorption is often adopted. This may lead to an overestimation or ...
Agenda voor de Toekomst – Waves in the estuary: analysis of wave measurements at Saeftinghe Flanders Hydraulics
One of the questions within the Agenda for the future research is the importance of waves in the estuary. To estimate these, terrain measurements are necessary. Within project 14_082 : “Waves in the estuary”, several measurement campaigns are foreseen, both in the Western Scheldt (Saeftinghe, Hooge Platen) as in the Sea Scheldt (Appels, Notelaer). This report describes the measurements performed at the location of Saeftinghe, in combination ...
Numerical simulation of wake effects in the lee of a farm of wave energy converters Ghent University
The contribution of wave energy to the renewable energy supply is rising. To extract a considerable amount of wave power, Wave Energy Converters (WECs) are arranged in several rows or in a 'farm'. WECs in a farm are interacting (e.g. The presence of other WECs influence the operational behaviour of a single WEC) and the overall power absorption is affected. In this paper wake effects in the lee of a single WEC and multiple WECs of the ...
Coherent relativistic wake wave of a charged object moving steadily in a plasma University of Antwerp
Nonlinear electron plasma waves driven by a finite-charged particle pulse or rigid object moving at relativistic speeds are investigated. Quasi-stationary smooth and spiky wake waves comoving with the object are found. Localized soliton-like solutions are also shown to exist. Relativistic effects tend to prevent their formation because of the electron mass increase. The application of the very-large-amplitude wake density waves as a source of ...
Agenda voor de Toekomst – Waves in the Scheldt estuary: analysis of wave measurements at Appels (Dendermonde) Flanders Hydraulics
One of the questions within the "Agenda voor de Toekomst" research is the importance of waves in the estuary. Waves are important as they can have an influence on the hydraulic load on river banks (and dikes). These hydrodynamic forcing can have morphological effects (erosion) on intertidal areas and therefore influence the ecological role of tidal flats and marshes. To estimate this, field measurements are necessary. Within project 14_082 : ...
WAVE STEEPNESS AND ROGUE WAVES IN THE CHANGING CLIMATE IN THE NORTH ATLANTIC KU Leuven
© 2015 by ASME. Wave steepness is an important parameter not only for design and operations of marine structures but also for statistics of surface elevation as well as occurrence of rogue waves. The present study investigates potential changes of wave steepness in the future wave climate in the North Atlantic. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) uses four scenarios for future greenhouse gas ...
Three-Dimensional MHD Wave Propagation and Conversion to Alfvén Waves near the Solar Surface. I. Direct Numerical Solution KU Leuven
The efficacy of fast - slow MHD mode conversion in the surface layers of sunspots has been demonstrated over recent years using a number of modelling techniques, including ray theory, perturbation theory, differential eigensystem analysis, and direct numerical simulation. These show that significant energy may be transferred between the fast and slow modes in the neighbourhood of the equipartition layer where the Alfvén and sound speeds ...
