Nazeer, N. (author)The aerospace industry is an ever-evolving field that has seen many technological advances over the past decades. The desire for aircraft to be not only efficient and reliable but also cheaper and safer has brought about many proposals across the industry. One of these advances is towards morphing aircraft wings to make wings lighter, more...doctoral thesis 2022

Goselink, Niek (author)This thesis covers the experimental characterisation of a multi-nozzle research combustor capable of achieving flameless combustion (FC). The combustor is operated with methane as fuel and air as the oxidiser, under an overall lean equivalence ratio ranging from 0.6-0.9. The work focused on designing and applying different experimental...master thesis 2022

Tieleman, O.C. (author)Flood gates form an essential part of many flood defence systems in coastal areas. During storm events, these gates are subjected to extreme loads from various sources. This dissertation addresses the dynamic behaviour of flood gates induced by wave impacts. A semi-analytical fluid-structure interaction model is developed to predict vertical...doctoral thesis 2022

Ubbens, Otmar (author)Crucial to the behaviour of a Nitrogen-Vacancy (NV) centre are its excited state cyclicities, determining the ability to perform high fidelity readout, spin-photon entanglement generation or fast spinpumping. This work presents a unified model to predict these excited state cyclicities over a wide range of strain, electric field, magnetic field...master thesis 2022

Ma, Sebastiaan (author)The Port of Rotterdam experiences large amounts of siltation from the upstream rivers in its basins and canals every year. Furthermore, container vessels increase in size every decade and therefore require a larger navigational depth. These two factors cause the yearly amount of dredged material to increase. Currently, mainly trailing suction...master thesis 2022

Buitelaar, Maarten (author)A dam-break wave can result in considerable damages and casualties. Events that can lead to such waves include dike and dam breaches, storm surges and impulse waves. Dutch history is familiar with a number of coastal dike breaches but also river dike breaches have occurred, resulting in dam-break waves reaching far inland. Beyond the Netherlands...master thesis 2022

van Dalen, Lyke (author)In this thesis a method of combined PIV and LIF experiments on the Turbulent/Non-Turbulent interface (TNTI) of a round jet is presented.<br/>By varying the distance from the nozzle in the measurements, the Kolmogorov scale of a large range of Reynolds number (2×10<sup>3</sup> ≤ Re ≤ 48×10<sup>3</sup>) is kept constant, allowing for a constant...master thesis 2022

de Beun, Martin (author)Lebbeus Woods was an experimental architect best known for his visionary drawings. His entry into the field of experimental architecture was enabled by the conditions in which the field found itself in the 1970s. Through drawing, Woods explored ideas and hypotheses which were unbound from conventional limitations. The field of architecture has...student report 2022

van der Zee, Tijs (author)When sailing in heavy seas, it happens that the water washes over the bow. This shipping of water is generally divided into two types. The term white water is used when the water is more of a spray and is generally harmless. Green water is more violent and can pose a danger to the crew and structures on board. <br/><br/>Research on green water...master thesis 2022

Ciolini, Matteo (author)The plasma behaviour in an air-propelled Hall thruster (SITAEL HT5k) is investigated by means of numerical modelling and experimental measurements. The air plasma employed (nitrogen/oxygen mixture) is firstly chemically characterized, identifying the most relevant species produced: four neutrals (N<sub>2</sub>, N, O<sub>2</sub>, O), four...master thesis 2022

Aouragh, Bilal (author)After decades of exploitation of hydrocarbons, the offshore facilities constructed for this purpose are nearing the end of their design life and/or economic operation. According to international law, these offshore structures need to be completely removed. Decommissioning of the substructures often requires for soil to be removed in piles to...master thesis 2022

Solbes Ferri, Irene (author)The objective of this master project is to improve the current SHM techniques for global damage identification of beam-like composite structures. The studied damage diagnosis method is based on structural vibrations from which the modal parameters are obtained. The literature study provides an overview of the most common vibration-based damage...master thesis 2022

Schildkamp, Roderick (author)With the increased focus on sustainability, aircraft are designed to reduce their emissions. One way to accomplish this is by increasing the wing aspect ratio, thereby increasing the aerodynamic efficiency, however this is not without consequences. Increased aspect ratio wings have a higher structural mass, are more susceptible to gust and...master thesis 2022

Zahoor, Y. (author)Modern helicopters are equipped with rotor blades with exposed linkages, swashplates, and mechanical components. While such rotor blades have proved to be highly reliable, they are the leading cause to generate noise and vibration. In addition, the drag due to exposed linkages and hinges affects the helicopter performance. To overcome these...doctoral thesis 2022

Tambe, S.S. (author)Boundary-layer instability induces spiral vortices on rotating cones. As they grow along the cone, the vortices enhance mixing of high- and low-momentum fluid, and subsequently, cause the boundary-layer to transition into a turbulent state. This transition process is scientifically enticing as it is one of the classical problems in fluid...doctoral thesis 2022

MAHAJAN, SAURABH (author)In recent years, there has been a lot of focus on system identification using vibration data instead of building mathematical models based on domain knowledge. The Sparse Identification of Nonlinear Dynamical System (SINDy) is a method that has been a great tool to identify the nonlinear dynamics. Therefore, in this report, the nonlinear systems...student report 2022

de Koster, P.B.J. (author), Koch, Jonas (author), Schulz, Olaf (author), Pachnicke, Stephan (author), Wahls, S. (author)Recently, a nonlinear Fourier transform-based Kerr-nonlinearity identification algorithm was demonstrated for a 1000 km NZDSF link with accuracy of 75%. Here, we demonstrate an accuracy of 99% over 1600 km SSMF. Reasons for improved accuracy are discussed.conference paper 2022

Snieder, J. (author), Dielen, Marc (author), van Ostayen, R.A.J. (author)Roll-to-plate nanoimprinting with flexible stamps is a fabrication method to pattern large-area substrates with micro- and nanotextures. The imprint consists of the preferred texture on top of a residual layer, of which the thickness and uniformity is critical for many applications. In this work, a numerical model is developed to predict the...journal article 2022
