Schipper, Jurrien (author)Modelling of Floating Offshore Wind Turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating structure, which makes the dynamic response of the whole system highly complex. A variety of numerical approaches can be used to predict this response.<br/><br/>The frequency...master thesis 2023

Pasolari, R. (author), Ferreira, Carlos (author), van Zuijlen, A.H. (author)In the field of computational aerodynamics, it is vital to develop tools that can accurately, but also efficiently, simulate the flow around bluff objects and calculate the aerodynamic forces acting on them. When strong body–vortex interactions take place, the simulations become more demanding, since complex phenomena appear. To address this...journal article 2023

Hoogewerf, Guus (author)Three-component seismometers deployed on the sea bed have been used for many years. These so-called ocean bottom seismometers (OBS) are used to register both compressional and shear waves. The recorded seismic information is used to enhance our understanding of areas of interest located offshore, like hydrocarbon reservoirs, mid oceanic ridges,...master thesis 2022

Bertazzi, A. (author), Bierkens, G.N.J.C. (author), Dobson, P. (author)Piecewise deterministic Markov processes (PDMPs) are a class of stochastic processes with applications in several fields of applied mathematics spanning from mathematical modelling of physical phenomena to computational methods. A PDMP is specified by three characteristic quantities: the deterministic motion, the law of the random event times...journal article 2022

O'Driscoll, Owen (author)Oceans play a vital role in the regulation of Earth's intricate climate system. The majority of gas and energy exchanges occurring at the ocean-atmosphere interface are driven by small-scale, O(1 km), coupled processes. Despite its importance, too few observations have been able to capture the ocean-atmosphere coupling at scales smaller than O...master thesis 2021

Sripathy, Kiran (author)Commercial FSI solvers employ partitioned FSI, wherein CFD and CSM solvers are used sequentially to resolve the coupling of interface displacement and stress/force. For strongly coupled problems, multiple sub-iterations of both the solvers are required for a stable and accurate solution. IQN-ILS framework requires fewer sub-iterations for...master thesis 2021

(author)Coupled nanomechanical resonators made of two-dimensional materials are promising for processing information with mechanical modes. However, the challenge for these systems is to control the coupling. Here, we demonstrate strong coupling of motion between two suspended membranes of the magnetic 2D material FePS3. We describe a tunable...journal article 2021

Doss, Arnav (author)Floating breakwaters are applicable in several offshore applications to protect downstream structures from excessive wave loads and to reduce their motion response. This thesis investigates the impact of the leading platform, functionally a breakwater, on the RAOs and response of the platforms behind it in frequency domain. The structures are...master thesis 2020

Schröder, Casper (author)Code quality of software products often degrades while they grow. Counteracting the degradation of code quality or improving it requires immense effort. Tools that reduce this effort are a hot topic in software engineering research. Software Modularization in particular aims to aid in the process of improving the quality of code structure, by...master thesis 2020

Arapakis, Takis (author)In recent years, the need to reduce the global warming of the planet has become more imperative than ever. Global warming and, at local scale, Urban Heat Island phenomena are among the primary effects of the increased building carbon emissions. Nevertheless, understanding and controlling the parameters which intensify, or mitigate, the...master thesis 2019

de Leeuw, Vincent (author)Wireless power transfer is getting more attention than ever before but seems to be lagging in the go-kart industry. Manufacturers are designing more electric powered go-karts, but haven’t found a proper solution for most of its major drawbacks. The added weight from the battery pack and the required time to recharge are just two of these major...master thesis 2019

Bandyopadhyay, S. (author), Prasanth, V. (author), Dong, J. (author), Bauer, P. (author)Inductive power transfer (IPT) is becoming increasingly popular in stationary electric vehicle (EV) charging systems. In this paper, the influence of the different IPT coupler geometries on the performance factors such as efficiency, power density, misalignment tolerance, and stray field is studied. Four different coupler topologies, namely...journal article 2019

Farhadi Machekposhti, D. (author)Classical human-engineered transmission mechanisms such as linkages, gears, and couplings are well established designs which made out of multiple parts and rigid hinges. However, these mechanisms impose disadvantages such as wear, friction, low precision and reliability, need for assembly and lubrications, and difficulty for miniaturization. By...doctoral thesis 2018
