van Burk, Sarah (author)The Dutch government has set a goal to phase out the use of natural gas by 2050. As a result, municipalities are focusing on implementing alternative heating strategies in certain neighbourhoods. However, districts with older building stocks are often neglected, raising concerns that city centers with older, poorly insulated buildings and high...master thesis 2023

Swen, Micha (author)The heat pump market is growing rapidly and new noise legislation creates issues for many people living in terraced housing and apartments. The assignment was to develop a sound reducing heat pump cover for Qventi. It should reduce the sound sufficiently, while being aesthetically pleasing and easy to assemble. It should also be smaller, lighter...master thesis 2023

Bulstra, Kasper (author)The main problem in density-based two-fluid optimization is the fact that the two fluids often mix in optimal designs. Therefore, state-of-the-art two-fluid heat exchanger optimization includes non-mixing constraints. However, the current non-mixing constraints can only impose a constant wall-thickness between the two fluids. Depending on the...master thesis 2023

Hoogerdijk, Tom (author)Hydrogen is seen as a potential energy carrier for the next generation of aircraft that will be more climate-friendly than the previous generation of kerosene-powered aircraft. Two types of hydrogen-based propulsion systems are currently foreseen for such aircraft: hydrogen combustion and hydrogen fuel cell. In addition to producing useful...master thesis 2023

Zimba, H.M. (author)Through precipitation retention and evaporation (by both interception and transpiration), woodlands play a significant role in the global moisture cycle. Evaporation is the largest, but at the same time, the most difficult flux to observe in a woodland. Accounting for woodland evaporation is important for hydrological modelling for the efficient...doctoral thesis 2023

Tan, C. (author)Historically, viruses have always been the causative agent of most human diseases. As one of the most devastating pandemics in human history, the COVID-19 pandemic, associated with SARS-CoV-2, is responsible for tens of millions of casualties in the world since the end of 2019. Meanwhile, it also has destabilized global economics. Therefore, in...doctoral thesis 2023

SHARMA, AKSHRA (author)This thesis aims to investigate the effects of contact pressure and type of deformations on the thermal contact conductance(h’) for dry metal-metal contacts. Also, an attempt is made to develope a thermal contact conductance estimation model for the same. The materials used in this thesis are metals (aluminium and tin). Several experiments are...master thesis 2023

Scoccimarro, Antonio (author)Hydrogen fuel cells are set to play an important role in decarbonizing the aviation sector. They operate at higher efficiencies than turbine engines, but their low operating temperature requires a dedicated thermal management system. The added drag, weight and parasitic power of such a system has a high impact on aircraft performance and its...master thesis 2023

Morete Barbosa Bertolo, V. (author)The use of materials in increasingly severe service conditions raises concerns about structural safety with respect to cleavage fracture. There are three main material-related challenges that structures face under harsh environments: 1) the trade-off between strength and toughness; 2) the ductile-to-brittle transition behaviour of BCC high...doctoral thesis 2023

van Heyningen, Maarten (author)Energy efficiency is a key goal for the Quooker system. To further increase the energy efficiency of the Quooker system, this study investigates a possible heat integration system where the waste heat from the refrigeration cycle for chilled drinking water is implemented to preheat water before entering the boiling water reservoir.<br/>Due to...master thesis 2023

Yan, R. (author)High-strength steel (HSS) has higher strength but lower ductility than mild steel. The cross-section of the structural members may be reduced using HSS instead of mild steel, provided the buckling of elements does not govern the failure. The reduced member size benefits the environment and economy by means of less energy consumption, less carbon...doctoral thesis 2023

van Loo, Julian (author)Energy poverty is an increasingly important issue. While vulnerable households are especially at risk in the energy transition, energy poverty effects of the transition are unknown. In Delft, a district heating network based on geothermal energy is planned. The distributive justice aspects of heat networks in the heating transition remain...master thesis 2023

QIU, Haodong (author)Hybrid structures consisting of FRP(fiber reinforce polymer) composite decks<br/>connected to a steel girder superstructure are gaining more attention by combining the stiffness of steel members with good fatigue endurance and high strength to weight ratio of FRP. However, when composite material FRP is exposed to elevated temperature,...master thesis 2023

DASOPOULOS, DIONYSIOS (author)Thick-section high strength steels (HSS) are widely used in engineering applications with requirements of high toughness and strength. Structural components are commonly joined by welding, known to significantly degrade the mechanical properties of steel due to changes in microstructure (e.g., grain size coarsening and martensite-austenite (M-A)...master thesis 2023

Dekker, Victor (author)Due to financial and environmental benefits, the interest in high-temperature heat pumps, producing heat sinks above 100 °C, is rising. Research is intensifying, and technology is developing fast. However, of all the components of the heat pump cycle, the oil management system seems to be the least investigated, even though 12% of the faults in...master thesis 2023
