de Hoog, E. (author)Hydraulic transport pipelines are used in dredging, (wet) mining and deep sea mining. These pump-pipeline systems are typically designed using steady-state principles. However, recent cases have shown that steady-state design does not always guarantee stable pipelines. Transients like self-amplifying density waves have shown to be able to...doctoral thesis 2024

Elferink, Amber (author)Moving through immersive virtual reality (VR) is commonly achieved by physically walking in the real room or using other techniques like an omnidirectional treadmill or walk-in-place. Roomscale walking is most similar to normal walking but is limited by physical space. However, other techniques can cause user experience issues such as VR...master thesis 2024

Miret Marco, Jorge (author)This research addresses the challenge of improving aerodynamic performance by delaying flow separation using deployable vortex generators (VGs) actuated by shape memory alloys. These VGs combine passive and active elements to enhance mixing within the boundary layer, restoring momentum near the wall and minimizing separation in an Adverse...master thesis 2024

Mandalahalli, M.M. (author)Bubbly flows are ubiquitously found in natural systems and are widely used in (bio)-chemical and energy-producing processes. A variety of design options, ease of maintenance, and a large operability window make bubble columns a commonplace across industries, ranging from oil processing to biotechnology and electrolyzers. Despite their wide...doctoral thesis 2024

Janssen, D. (author)The dissertation explores the use of emergency measures, particularly the BresDefender, to prevent or delay levee failure and mitigate the impacts of floods, focusing on the Netherlands' flood protection systems. Levees are vital for protecting low-lying areas, but there's always a risk of failure, leading to significant societal and material...doctoral thesis 2024

Okatan, Selin (author)The River Dommel is a modest-sized and ecologically sensitive stream located in the southern region of the Netherlands, covering a catchment area of 153,000 hectares. Its primary water source is rainwater, supplemented by a minor contribution from groundwater, particularly notable in the upstream portion of the catchment. Nevertheless, rainwater...master thesis 2024

Mathoera, Winand (author)Amsterdam Airport Schiphol characterises itself as a major hub in Europe. Its network is not sustainable with only the Dutch catchment area. Instead, it relies on transfer passengers. When new tax regimes and policies are implemented to combat the environmental impacts of the airport, a change in passenger flows could affect Schiphol’s network...master thesis 2024

Gonzalez Martinez, Pablo (author)This thesis explores the use of physics-informed neural networks (PINNs) to reconstruct the flow fields in a pool fire flame, a canonical configuration in non-premixed combustion. Due to the difficulty in obtaining adequate experimental characterizations of such flows, reacting flows like pool fires stand in need of novel methods capable of...master thesis 2024

Boorsma, Reinder (author)The Wadden Sea is of great ecological importance. Key elements in the Wadden Sea are the extensive intertidal flats. These contain vast amounts of life, serve as feeding grounds for millions of birds, and provide ecosystem services such as coastal protection. It follows that it is important to be able to understand and predict how these vital...master thesis 2024

Mironov, Stas (author)A network, is defined as a collection of nodes interconnected by links. When this topology changes through time, we call it a temporal network. A specific class of networks, with only two types of nodes with no connections between one kind, is the bipartite network. An example is a telecommunications network, where nodes represent...master thesis 2024
