Gonzalez Saiz, G. (author)Experimental aeroelasticity has been hindered by the intrusivity of measurement equipment and complexity of the experimental setups. Advancements in hardware development have been encouraging optical tracking techniques to replace cross correlation approaches in experimental aerodynamics. However, digital image correlation (DIC) is still the...doctoral thesis 2023

Thedens, Paul (author), Schmehl, R. (author)Similar to parafoils, ram-air kites are flexible membrane wings inflated by the apparent wind and supported by a bridle line system. A major challenge in estimating the performance of these wings using a computer model is the strong coupling between the airflow around the wing and the deformation of the membrane structure. In this paper, we...journal article 2023

van Essen, S.M. (author), Seyffert, Harleigh C. (author)Green water and slamming wave impacts can lead to severe damage or operability issues for marine structures. It is therefore essential to consider their probability and loads in design. This is difficult, as impacts are both hydrodynamically complex and relatively rare. The complexity requires high-fidelity modeling (experiments or CFD),...journal article 2023

Reuchlin, S.P.A. (author), Joshi, R. (author), Schmehl, R. (author)The majority of remote locations not connected to the main electricity grid rely on diesel generators to provide electrical power. High fuel transportation costs and significant carbon emissions have motivated the development and installation of hybrid power systems using renewable energy such these locations. Because wind and solar energy is...journal article 2023

Mitrotta, F.M.A. (author), Sodja, J. (author), Sciacchitano, A. (author)This study describes a novel measurement approach for combined flow and structural measurements in wind tunnels using robotic volumetric particle tracking velocimetry (PTV). The measurement approach is based on the application of a particle tracking algorithm on images including flow or structure tracers, where the latter are implemented by...journal article 2022

Colomés, Oriol (author), Verdugo, Francesc (author), Akkerman, I. (author)In this work we present a novel monolithic Finite Element method for the hydroelastic analysis of very large floating structures (VLFS) with arbitrary shapes that is stable, energy conserving, and overcomes the need of an iterative algorithm. The new formulation enables a fully monolithic solution of the linear free-surface flow, described by...journal article 2022

Angka Bayu Putranto, Angka (author)This thesis concerns a numerical investigation for the stabilization (delay of laminar-to-turbulent transition) of ows over a at plate with a meta-unit of a possible metamaterial. The type of instability studied is that due to small disturbances in an incompressible, two-dimensional boundary layer. The linear growth of the disturbance in the...master thesis 2021

Bockstael, Marnix (author)Marine structures can sustain damage due to violent wave impacts that are characterized by complex dynamics involving both water and air. Methods that predict impacts loads for structural design often assume the water as incompressible. These predictions can be inaccurate during impacts where air is entrained in water, as that greatly increases...master thesis 2021

de Klerk, Kasper (author)The size of vessels has increased significantly over the last decades and will increase even further in the decades to come. This trend is mainly visible in the size of container ships. A decade ago the largest container ship had a capacity of 13.500 TEU, nowadays the largest container ship has a capacity of almost 24.000 TEU. The capacity of...master thesis 2021

Rietema, Roald (author)Recent decades, an ongoing trend has emerged in the upscaling of wind turbines in order to compete with traditional energy resources. For conventional wind turbines, aside from improving safety, the driving factors for new designs have always been increased efficiency and performance. This has led to novel wind turbine designs comprising thin...master thesis 2019

Mathew, Maria (author)This thesis studies a novel mesh deformation method based on radial basis functions to improve mesh quality in regions with small wall clearances. For fluid-structure interaction problems or imposed motion CFD problems, the usually fixed Eulerian fluid meshes have to undergo deformation to conform to the deforming structure. In such cases, it is...master thesis 2019

Derksen, Adriaan (author)Recent innovations in the off-shore wind industry have lead to bigger wind turbines and taller support structures. These towers can suffer from vortex-induced vibrations (VIV). The present work couples the open-source CFD solver OpenFOAM with a structural solver to investigate these fluid-structure interactions (FSI) effects in more detail. 2D...master thesis 2019

Qu, Y. (author)Vortex-induced vibration (VIV) is awell-known phenomenon for civil and offshore structures. Currently, the prediction of this type of vibration in practice currently mainly relies on the force-decomposition method. However, the limitations of this method have restricted the applicability of the method, and alternative models are therefore needed...doctoral thesis 2019

Maljaars, P.J. (author)Higher efficiencies, higher cavitation inception speeds and reduced acoustic signature are claimed benefits of flexible composite propellers. Analysing the hydrodynamic performance of these flexible propellers, implies that a coupled fluid-structure interaction (FSI) computation has to be performed. An FSI coupling can be monolithic, which means...doctoral thesis 2019
