Hussain, Mohammed Muaaz (author)The advent of global warming has brought an increased interest in non-conventional sources of energy, one of which is nuclear energy. Threatening the almost year-round functioning of nuclear power plants are Flow-Induced Vibrations (FIV). One such mechanism, Vortex-Induced Vibration (VIV), holds importance in areas of cross flow in nuclear power...master thesis 2021

van Hoof, Sjoerd (author)At the moment, the world is at the verge of an energy transition. One of the most promising green resources is solar energy, which is a rapidly growing market. However, to fully use its potential of economy of scale, the application of offshore floating solar should be explored. A promising option is the use of a flexible type of Very Large...master thesis 2021

Helsdingen, Martijn (author)A new semi-analytical model is developed to predict the dynamic response of slender gates in combination with an overhang, which are subjected to standing waves. Still little is known for these types of gates for this specific forcing type. The semi-analytical model is still in its development phase and must be validated on its performance. This...master thesis 2021

Srikanth Vasudevan, Srikanth (author)High Altitude Long Endurance (HALE) configurations have gained much popularity in the recent past. Although, HALE aircraft enable efficient and environmental-friendly flying, they necessitate a large Aspect-Ratio wing. These slender structures are prone to large, non-linear deformations which further increase the unsteady nature of aerodynamic...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

Lai, Yu-Jui (author)This research studies the fluid-structure interaction (FSI) of compliant surfaces in air flows, with an objective of finding possible turbulent viscous drag reduction. A compliant surface is a thin layer of viscoelastic material drawing inspiration from dolphin epidermis, which was thought to have drag-reducing capabilities by Gray (1936)....master thesis 2021

Zou, P. (author), Bricker, J.D. (author), Uijttewaal, W.S.J. (author)The interaction between an oceanic internal solitary wave (ISW) and a prototype submerged floating tunnel (SFT) is numerically investigated. Effect of oceanic internal solitary wave amplitude, the relative distance of the SFT to the pycnocline, cross-sectional geometry of the SFT, and the density ratio of the two fluid layers are analyzed. At...journal article 2021

Tieleman, Orson (author), Hofland, Bas (author), Tsouvalas, A. (author), de Almeida Sousa, E. (author), Jonkman, Sebastiaan N. (author)This paper establishes a computationally efficient model to predict flood gate vibrations due to wave impacts including fluid–structure interaction. In contrast to earlier models, composite fluid domains are included to represent the situation of a flood gate in a dewatering sluice with the presence of an overhang that causes the confined-wave...journal article 2021

Thari, Ali (author), Pasquariello, Vito (author), Aage, Niels (author), Hickel, S. (author)We present an adaptive reduced-order model for the efficient time-resolved simulation of fluid–structure interaction problems with complex and non-linear deformations. The model is based on repeated linearizations of the structural balance equations. Upon each linearization step, the number of unknowns is strongly decreased by using modal...journal article 2021

Casquero, Hugo (author), Bona-Casas, Carles (author), Toshniwal, D. (author), Hughes, Thomas J.R. (author), Gomez, Hector (author), Zhang, Yongjie Jessica (author)We extend the recently introduced divergence-conforming immersed boundary (DCIB) method [1] to fluid-structure interaction (FSI) problems involving closed co-dimension one solids. We focus on capsules and vesicles, whose discretization is particularly challenging due to the higher-order derivatives that appear in their formulations. In two...journal article 2021

Qu, Y. (author), Metrikine, A. (author)This paper is first of the two papers dealing with the nonlinear modelling and investigation of coupled cross-flow and in-line vortex-induced vibrations (VIVs) of flexible cylindrical structures. As a continuation of the previous work (Qu and Metrikine in Ocean Eng 196:106732, 2020) where a new single wake oscillator model was proposed and...journal article 2021

van Zanten, Renée (author)Waves impacting on maritime structures can cause damage which endangers the environment around these structures. Due to high hydrodynamic loading, structures can enter the plastic regime, resulting possibly in structural failure. The understanding of the principles related to this structural failure due to waves is a key concept in this research...master thesis 2020

Helsdingen, Martijn (author)Vertical sliding valves that are part of a filling and emptying system of a lock are often subjected to an underflow of water during emptying and filling. The flow induces time varying forces on the structure which leads to dynamic behaviour of the valve. Whether the structure is in the range of resonance and what the amplitude of the vibrations...student report 2020

Krishnan, Navaneetha (author), Viré, A.C. (author), Schmehl, R. (author), van Bussel, G.J.W. (author)A novel immersed boundary method based on a domain decomposition approach is proposed in the context of a finite element discretisation method. It is applicable to incompressible flows past rigid, deforming, or moving bodies. In this method, unlike most immersed boundary methods, strong boundary conditions are imposed in the regions of the...journal article 2020

Bertocchi, F. (author)Flows in rod bundles are common to many industrial applications such as heat exchangers or some types of nuclear reactors. The core of many classes of nuclear reactors can be easily sketched as a bundle of rods, the fuel pins, inmmersed in an axial ow of coolant that removes the heat produced by the fission reaction. Coupling this geometry to an...doctoral thesis 2020
