Wasim, A.M.K.K. (author)For μCHP applications, micro gas turbines offer many potential advantages in comparison to other conver- sion technologies due to their compact size and high specific power, low vibration and noise, low mainte- nance requirements, low emissions and high-grade residual thermal energy. Optimisation of MTT compressor with a vaneless diffuser (OCVLD...master thesis 2017

Bremm, M.J. (author)The mechanism of three-dimensional shock control bumps (SCBs) to reduce wave drag is widely understood. Further, it has been claimed potential for passive flow control of transonic buffet. Although the underlying mechanisms of how SCBs favourably influence buffet onset are thought to be understood in broad terms, no experiments of SCBs in an...master thesis 2017

Floris, C.E. (author)Damage in materials and structures is unavoidable, leading to the time deterioration of its functional properties (e.g. barrier, load bearing, aesthetics) and ultimate repair or replacement. Lifetime extension can be achieved by using materials with initially higher performance or using materials that can repair themselves (self-healing). The...master thesis 2017

Hermsen, R.J.G. (author)To launch a rocket to the edge of space using a pressure fed rocket system with liquid oxygen as propellant, you need to know exactly how much pressurant gas (helium) you need to take along. In this thesis a practical investigation on cryogenic tank pressurization is conducted together with DARE. The measurement results are used to validate...master thesis 2017

Marchena, C.J. (author)This research aims to investigate the validity of the standard power curve (i.e. measured power curve M-PC) in non-standard wind conditions and the integration of those results into recommended practices for future warranty negotiations. The Power Performance Testing (PPT) is carried out on a ABC1 with rotor diameter between 105-110m and rated...master thesis 2017

Francés Mollá, V. (author)Turbomachines have experienced a fast development over the last years, and are present in a wide range of devices involved in the generation of electricity and the transportation sector. Current challenges in both sectors have driven quite a number of developments regarding the increase of efficiency and use of new types of devices. Those...master thesis 2017

Deccia, C.M.A. (author)Exoplanets have been detected for more than 15 years. In the vast majority of instances, this has been accomplished through indirect observation. Such methods include among others the observation of radial velocity, transit photometry, and timing variations. These techniques allow for the vast majority of exoplanet detections up to date. An...master thesis 2017

Mehmood, H. (author)In existing modular adaptive control approaches, the effects of external disturbances such as atmospheric turbulence are often not considered. In real-life flight applications, stochastic atmospheric disturbances can severely degrade the performance of these approaches, resulting in undesired and unpredictable control behavior. In this thesis,...master thesis 2017

Heijkoop, E. (author)This thesis presents the results of a developed density inversion tool, which estimates lunar crustal density anomalies from Bouguer anomalies. The tool is run through a number of tests for verification, culminating in the forward modeling and subsequent inversion of synthetic density anomalies, showing a > 97% recovery of the original density...master thesis 2017

Haneveer, M.R. (author)The ballistic coefficient β of a satellite indicates the influence atmospheric drag has on the orbital decay of said satellite. The method developed in this study estimates the ballistic coefficients of 1U CubeSats by analysing both its historical TLE data and the density it experienced along its trajectory according to the empirical density...master thesis 2017

Boven, R.V.T. (author)An interesting concept related to photovoltaic energy is Concentrated Photovoltaics (CPV), in which sunlight is focussed on a PV cell through lenses and mirrors, thereby increasing the incident irradiance on the PV cell. Solar concentration is proven to not only increase the output power of PV cells, but also to increase the electrical...master thesis 2017

de Boer, T. (author)Both experimental and numerical studies have shown that the crack-bridging is one of the most significant mechanism contributing to the fracture toughness of natural materials like nacre and bone. This study aims to explore if additive manufactured lattice structures can be used to bridge fatigue cracks as well, thereby improving the fracture...master thesis 2017

Mishra, V. (author)Automated fibre placement technology has made possible to place bands of composite fibre tows along curvilinear path to create laminates with spatially varying stiffness properties called variable stiffness panels. These panels have shown improvement in stiffness properties, buckling load and post buckling failure load, over conventional...master thesis 2017

Ran, J. (author)Strut-braced wing aircraft are believed to have great potential for the future of large passenger air transport with regard to fuel burn reductions due to the combination of high structural and aerodynamic efficiency. Strut-braced wings deviate from conventional wings in the fact that they employ additional bracing at certain span location away...master thesis 2017

Gonzalez de Diego, G. (author)Turbidity currents are an essential agent of sediment transport from shallow to deeper waters. Detailed measurements of the velocity field or particle concentration are only available by means of accurate numerical simulations. In this thesis, a DNS solver for turbidity currents is presented based on the MEEVC scheme, a mass, energy, enstrophy...master thesis 2017

Shroff, A. (author)Within 100 years of the Wright Brother's first flight, we are already approaching the top of aviation’s technological S-curve. Breakthrough technical improvements have resulted in an undeniable increase in efficiency and range, but today’s aircrafts are still relatively inefficient resulting in a large amount of air and noise pollution. In order...master thesis 2017
