Garry Yuan Kwan, Garry (author)Idling instabilities of large wind turbines in extreme winds is a relatively well known problem for manufacturers, at least in terms of the results in calculations. However, many are still sceptical of how realistic such instabilities are in actuality due to limitations in the current state of the art aeroelastic tools.<br/>The overall aim of...master thesis 2017

Wanthanadamkerng, Thawatchai (author)The use of vortex generators (VGs) is a prevailing technology in large modern wind turbines due to its potential to increase wind turbine annual energy production [39] by re-energizing the momentum energy in the boundary layer and, as a consequence, delay the flow separation. Many researchers have been extensively studying the effects of VGs on...master thesis 2017

Li, Ang (author)The aim of this thesis is to evaluate the influence between the two counter-rotating VAWT rotors with the Double Actuator Cylinder (DAC) model which will be validated against the panel code. The DAC model is developed from the original Actuator Cylinder (AC) model which includes the Modified-Linear (Mod-Lin) correction. The original AC model for...master thesis 2017

Chavez Olalla, Juan (author)Aftercare of sanitary landfills represents a burden for future generations, for emission potential of leachate and gases remains for hundred of years. Treatment methods have to be developed in order to accelerate waste degradation and reduce emission potential preferably within the time-span of one generation. Aeration seems a promising...master thesis 2017

Sellés Alsedà, Dídac (author)As technology advances, industry and academia rely more and more on the output of computer simulations or physical experiments of engineering systems under development. In some cases, the relationship between input and output of a system under study is too complex to model through analytical expressions or numerical methods. In other cases,...master thesis 2017

Tan, Hong (author)Offshore wind farms in Bohai Bay may be exposed to sea ice. The possible development of ice-induced vibrations can result in periodic high amplitude oscillations of the structure, which can significantly contribute to the fatigue of the structure. The main objective of this thesis is to investigate the mitigation effects of ice-induced...master thesis 2017

Clarke, Jules (author)This thesis elaborates on a newly developed Fully Implicit simulation model that captures the full coupling of reaction kinetics and fluid dynamics during carbonate matrix acidizing at an extensive (field) scale. The framework describes the physical processes at reservoir scale, by accounting for upscaled pore-scale-based quantities for reaction...master thesis 2017

Jamodkar, Ajay (author)Recent innovations in Electric Vehicles (EVs) will potentially change the future of the transportation industry. They will diversify the energy mix and reduce the dependence on fossil fuels. However, use of EVs only shifts the source of CO2 production to electricity generation plants. A smart solution to overcome this problem is the use of...master thesis 2017

Gámir Huguet, Carlos (author)A novel continuum damage mechanics model for 2D woven fabrics has been developed and implemented in a VUMAT subroutine for Abaqus/Explicit. The model takes into account the shear non-linearity, the toughening mechanisms associated to tensile failure, and the influence of shear stresses in the initiation and propagation of tensile damage. <br/>...master thesis 2017

Subhedar, Nupur (author)Recently an oxidation and reduction cycle of metals has been proposed as alternative for liquid fuel combustion. Out of several possible metals iron is an interesting candidate because the oxide does not form making it more easy to develop a cyclic process. As a first building block towards a computation or particle dust clouds here a...master thesis 2017

Ketelaars, Martijn (author)During aircraft design,multiple tools are utilised to inspect the performance of the configuration. As the design matures, higher fidelity analyses are conducted to predict the flight dynamics of the aircraft. These analyses are conducted by using semi-empirical relations, numerically analysing flow behaviour, conducting wind-tunnel tests and...master thesis 2017

Jimenez Lluva, David (author)Electric Propulsion (EP) has become one of the most efficient technologies for spacecraft propulsion. In contrast to conventional chemical propulsion, the low thrust force generated by EP thrusters can deliver a momentum transfer to the spacecraft that is up to twenty times greater, for an equivalent propellant expenditure. Despite decades of...master thesis 2017

Liu, Riqian (author)There are two existing surface passivation principles. Passivation of unsaturated Si bonds is called chemical passivation. Surface passivation can also be achieved by shielding the minority charge carriers from the semiconductor interface by means of an electric field. This method is referred to as field-effect passivation. <br/>To test the...master thesis 2017
