Op 1 februari 2016 heb ik een trillingsmeting uitgevoerd aan de fundering van en de bodem rondom een 3 MW windturbine in het Distripark Waddinxveen. De<br/>windsnelheid tijdens de meting was gemiddeld 15 m/s met pieken tot 23 m/s.<br/>Dit rapport beschrijft de meetopstelling, de postprocessing en de bevindingen.<br/>De meetopstelling bestond uit...

Tides, currents, wind, waves, and sea level (surge) influence each other in several ways. These interactions are often not accounted for. We here review some recent papers that report results from coupled modelling with the aim to get an impression of how large coupled effects might be, and in which regions and under which circumstances they...

Over the last five years a research program has been carried out to assess the performance of the spectral wave model SWAN in the Wadden Sea so that it may be used for the transformation of offshore wave conditions to wave boundary conditions near the sea defenses (dikes and dunes). The assessment was done on the basis of extensive wave...

In practice, many people have to work together to develop and maintain a software system. However, the programmer’s key tool, the Integrated Development Environment (IDE), is a solo-tool, serving to help individual programmers understand and modify the system. Such an IDE does not leverage the knowledge other team members may have of the design...

The present study aims to assess the prediction of wave penetration into tidal inlets under ambient current in SWAN. The performance of SWAN in the modelling of wave-current interaction was studied for two field cases, namely Port Phillip Bay Heads, Australia, and the Amelander Zeegat in the Dutch Wadden Sea. In-situ wave observations were...

The subiteration method which forms the basic iterative procedure for solving fluid structure-interaction problems is based on a partitioning of the fluid-structure system into a fluidic part and a structural part. In fluid-structure interaction, on short time scales the fluid appears as an added mass to the structural operator, and the...

Numerical simulation of fluid-structure interaction generally requires vast computational resources. Paradoxically, the computational work is dominated by the complexity of the subsystem that is of least practical interest, viz. the fluid. The resolution of each of the many small-scale features in the fluid is prohibitively expensive. However,...

In the period 1997-2007, an extensive wind and wave measuring campaign has been carried out on Lake IJssel and Lake Sloten in The Netherlands. The aim of this campaign was to gather and analyse welldocumented wind and wave measurements of high quality, for a range of fetch, depth and (strong) wind conditions. The data should serve a number of...

The necessity to associate two geometrically distinct meshes arises in many engineering applications. Current mesh-association algorithms are generally unsuitable for the high-order geometry representations associated with high-order finite-element discretizations. In the present work we therefore propose a mesh-association method for high-order...

The basic iterative method for solving fluid-structure-interaction problems is a defect-correction process based on a partitioning of the underlying operator into a fluid part and a structural part. In the present work we establish for a prototypical model problem that this defect-correction process yields an excellent smoother for multigrid, on...

The field of fluid-structure interaction is combined with the field of stochastics to perform a stochastic flutter analysis. Various methods to directly incorporate the effects of uncertainties in the flutter analysis are investigated. The panel problem with a supersonic fluid flowing over it is considered as a testcase. The stochastic moments ...

Within the framework of the CLASH-white spot tests, wave overtopping tests on a smooth sloping structure have been performed at UGent. 3 different geometries have been tested during these tests 1) simple smooth dike 2) simple smooth dike with a small vertical part (same crest level as geometry 1) 3) simple smooth dike with a small vertical part...

Subiteration forms the basic iterative method for solving the aggregated equations in fluid-structure-interaction problems, in which the fluid and structure equations are solved alternately subject to complementary partitions of the interface conditions. However, this subiteration process can be defective or inadequate, as it is endowed with...

Based on a database of laboratory data on wave overtopping (around 10,000 tests) a neural network technique is used for producing a generic prediction method. In the first database (around 7,000 tests) the following white spots were detected where additional tests could improve the generic prediction method. This report deals with the laboratory...

This report details the results of the second phase of the additional white spot tests undertaken by the University of Edinburgh. Part A was undertaken by Aalborg University who investigated the effect of wave obliquity. Edinburgh were commissioned to undertake a series experiments to determine the relative difference in overtopping...

Tests have been performed with low steepness and reshaping breakwaters at Ghent University and Aalborg University respectively. The reshaping breakwater is a type of breakwater where the information on overtopping is very limited. The additional tests are described in the following four reports: .. D24 – Part A: Effect of obliqueness, short...

The main objective of Workpackage 5 is to use numerical simulation of wave overtopping in order to solve the problem of suspected scale effects. A second, related, objective is to improve existing codes in such a way as they are able to simulate wave overtopping in a reliable way. The final, single, objective is to numerically model long waves...
