Winter, Theun (author)The surge in demand for inland vessel goods transportation has necessitated the operation of larger vessels with increased drafts. These larger vessels generate significant induced loads from their more powerful bow thrusters during berthing and mooring. These loads can lead to scour, which ultimately results in instability of the quay wall. To...master thesis 2024

Been, Coen (author)At the turbulent/non-turbulent interface (TNTI) of a jet flow, momentum is transferred from the turbulent jet fluid to the fluid at rest. This transfer is governed by two mechanisms. One of them is related to the large scales of the flow and the other relates to the small scales of the flow. Which of the two is dominant is still a point of...master thesis 2024

Alhaddad, S.M.S. (author), Suleman, M. (author), Kirichek, Alex (author), Chassagne, C. (author)Coandă-effect-based collection stands out as the foremost technology in polymetallic-nodule mining due to the absence of direct contact between the collector and the ocean floor. Yet, this collection method disturbs the ocean floor, and minimizing such disturbance is crucial from an environmental viewpoint. To this end, a solid understanding of...journal article 2024

(author), Titov, Oleg (author), Melnikov, Alexey (author), Paragi, Zsolt (author)There is still a limited number of high-redshift (z > 3) active galactic nuclei (AGNs) whose jet kinematics have been studied with very long baseline interferometry (VLBI). Without a dedicated proper motion survey, regularly conducted astrometric VLBI observations of bright radio-emitting AGN with sensitive arrays can be utilized to follow...journal article 2024

Giele, R.J.P. (author), Ayas, C. (author), Langelaar, Matthijs (author)Topology optimization methods are used to design high performance structural components that often have complex geometric layouts. In several industries, components are required to be cleanable, and for this research cleaning by jetting is considered. Thus, being able to ensure jet access on the entire surface of a structure is of interest in...journal article 2024

Numerical analysis of a parallel triple-jet of liquid-sodium in a turbulent forced convection regimeCascioli, E. (author), Kaaks, B.J. (author), Keijers, S. (author), Van Tichelen, K. (author), Kenjeres, S. (author)In the present study, we have applied a combined wall-resolving dynamic Large-Eddy Simulation (LES) (for the velocity field) and Direct Numerical Simulation (DNS) (for the temperature field) approach for mixing of parallel triple-jets with different temperatures of liquid sodium in a turbulent forced convection regime. Because of the high...journal article 2024

Houtkoop, Mariëtte (author)This research aimed to optimize the process parameters of small copper parts printed with binder jetting. The optimisation was distinguished by dividing the parameters in print and post-process parameters. Binder jetting is an additive manufacturing technique that combines layers of the material in powder form with a binder. After the printing...master thesis 2023

Mohan, Adithya Keshav (author)Ceramics are being explored as an alternative material by ASML to replace their stainless steel 316L (SS316L) reticle masking blades. Ceramics offer distinct advantages over stainless steel in the semiconductor industry. While stainless steel exhibits good mechanical strength, ceramics excel in electrical insulation and thermal conductivity,...master thesis 2023
