Baugh, Rebecca (author)
Collaboration between the Global South and Global North is inevitable. It can work. It can be emphatic, effective, and more equal. However, there is a deeply embedded history of colonialism involving power asymmetries that give rise to the dismissal of value systems, which pervert this type of collaboration from being truly realised. Hence,...

Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...

When containers are transported on synchromodal bookings from their origin to their destination, the transport supplier can decide which combination of trucks, trains, and ships to use. This gives transport suppliers many options to route the container through the synchromodal network. Current literature on the individual routing of containers...

In order to decarbonize the electricity grid, renewable energy sources must be utilised in con- junction with energy storage to provide ancillary services, which maintain electricity supply quality, reliability and restorability, whilst remaining aordable. Due to a lack of knowledge about the potential of stacking UK ancillary services and...

Computational fluid dynamics is nowadays one of the pillars of modern aircraft design, just as impor­tant as experimental wind tunnel testing. Very ambitious goals in regards to performance, efficiency and sustainability are being asked of the aviation industry, the kind that warrant a virtual exploration of the edges of the flight envelope....

Data is becoming more important because of the increased possibilities of analysis and the increase in possibilities of data sharing. Multi-party Computation or MPC is a privacy-preserving technology that enables anonymous data sharing between companies. This thesis identified quantifiable aspects of economic impact such as legal costs and...

The aim of this study is to analyse the influence of ply drop-off regions and related parameters on the VARTM cure-induced residual stress generation and related distortions within thick thermoset composites. These parameters include the resin pocket material properties and geometry, ply orientations and cure cycle parameters. By means of a...

In practice, many applications like traffic monitoring and smart grids rely on computing functions on privacy-sensitive data. In order to protect privacy-sensitive data and still keep the ability to compute any arbitrary function, multi-functional privacy-preserving data aggregation schemes have been created. These schemes, however, can be...

This research aims to determine the cost effectiveness of yacht emission reducing ret options through marginal abatement cost curves. A broad selection of five refit options is evaluated and implemented in the created tool. Using multiple scenarios by fluctuating fuel price and the implementation of hydrotreated vegetable oil (HVO), the effect...

As a part of a <i>Future Launcher Preparatory Programme</i> contract issued by the European Space Agency, the aerospace startup company Dawn Aerospace is developing an integral, additive manufactured (AM), liquid rocket engine. This 2.5 kN class engine is propelled by the storable propellants 90% hydrogen peroxide and kerosene and used in the...

Launch vehicle structures are commonly composed of cylindrical and conical shells, which are inherently sensitive to buckling. The axial compression experienced during launch can consequently be a sizing load case, so it is important to understand the axial buckling behavior of these shells. Experimental testing is an essential part of studying...

The aviation industry has set ambitious emission reduction targets for 2050. Following the success of electrification in the automotive industry, the potential of hybrid electric propulsion (HEP) has been the subject of many scientific projects. The energy and power of the electric systems that support the aircraft propulsion system are...

Sonneveld, Dave (author)
Compliant joints have significant advantages compared to rigid-body hinges due to a monolithic design and the absence of friction, which prevents effects like wear, backlash and stick-slip behaviour. However, the loading capability is often limited and the support stiffness generally decreases during rotation, caused by the use of solid leaf...

The goal of this thesis is to characterise diesel-ammonia combustion using a mean value first principle approach, and to implement this characterisation of diesel-ammonia combustion in a time domain two-stroke engine model. This model will be used to indicate the technical feasibility of diesel-ammonia as a marine fuel. The main research...

Gas turbines for power generation use lean premixed flames to adhere to the strict pollutant emissions regulations. Unfortunately, this often leads to thermoacoustic instabilities. These instabilities can lead to failure of system components, flame blow-off or flashback and a reduction in efficiency. Especially the high frequency transverse...

The IsoTruss is an interesting continuous fibre reinforced polymer composite design which is closely related to open lattice composite structures, although it is currently aimed mostly at civil applications. While it currently lacks applicability to the aerospace sector, its production process is easier to automate (or change the shape input...

The applicability of conflict rate models to controlled, structured, terminal airspace is investigated. A collision rate model is adapted to conflicts between flows of aircraft, and its validity is empirically confirmed. Conflicts are divided into between-flow conflicts and within-flow conflicts. Applicability to a terminal airspace without...

During berthing operations of ships, the horizontal thrusters cause a hydraulic load on the quay wall and bed. This could eventually lead to scour holes in the bed, which may affect the structural integrity of the quay wall. This thesis is about a numerical simulation of a bowthruster jet which is deflected by a quay wall and the focus of this...

The climate is changing and industries world-wide need to transform to assure a liveable earth for future generations. Within the construction sector, this requires a different approach and perspective on the life-cycle of civil engineering assets since the construction industry and its build environment is the world’s largest consumer of raw...

An essential step on the way to a circular economy is utilizing recycled materials for new products. Even though the use of recycled plastic has been increasing for the past decades, electronic products have been largely overlooked in this context. Currently, there are no design strategies on how to use recycled plastic in electronic products....
