Troost, Diederik (author)Jetted radial wells are a relatively new form of hydraulic stimulation for oil and gas wells, where small diameters holes extend radially from a wellbore. This technique for increasing well connectivity could also be applied to geothermal wells. Radials can be freely placed along a backbone well, making the design of an economically viable well...master thesis 2019

Pandey, Mayank (author)The Beam Dump Facility (BDF) is a new fixed target facility proposed to be installed in the North Area of CERN. Currently in its design phase, the BDF is aimed at the Search for Hidden Particles (SHiP) experiment, which purpose is to investigate the origin of dark matter and other lightly interacting particles. The BDF target/dump sits at the...master thesis 2018

Fatou Gomez, Javier (author)The computation of complex turbulent flows design optimization processes is currently limited by the lack of accuracy of Reynolds-Averaged Navier-Stokes (RANS) in massively separated flows and the infeasible cost of multiple Large-Eddy Simulation (LES) evaluations. A novel method is presented, injecting data from LES or other high-fidelity...master thesis 2018

Bernal Mencia, Pablo (author)In the framework of JAXA's MMX mission to explore the Martian moon of Phobos, an analysis of the stability of three-dimensional quasi-satellite orbits in the Mars-Phobos circular restricted three-body problem was conducted. For this analysis, notions of co-orbital motion, interpreted as the slow motion of the guiding center of the trajectory...master thesis 2018

Krijgsman, Wiegert (author)In the noiseless case, the identification of a grey-box model can be posed as a feasibility problem, i.e. determining if existent - and if so - finding a parameter vector such that the parametric model equals the actual model (or its associated input-output data). Being that in this thesis we are interested in continuous-time grey-box...master thesis 2018

Fodde, Iosto (author)Currently one of the major drawbacks of interplanetary travel is the cost of these types of missions. Mission to extra-terrestrial bodies require a large amount of propellant to complete, which often takes up a large part of the mass budget of the spacecraft. This requires larger launchers to be used to get the spacecraft into the required orbit...master thesis 2018

Blom, Martijn (author)In order to reduce the climate impact induced by the aircraft industry, the variability between cost optimized and climate optimized flight trajectories was evaluated. This was done to establish how the climate impact reduction affects the operating costs and vice versa. To evaluate the climate impact of air traffic, a climate-chemistry model...master thesis 2018

Fakhri Muhammad, Tubagus (author)Electric Vehicles (EVs) provide a promising sustainable clean mode of transportation with much fewer emissions compared to the traditional Internal Combustion Engine (ICE) vehicles. However, this can only be considered true if the energy sources used for charging EVs are also from clean energy form. Various Renewable Energy Sources (RES) are...master thesis 2018

Sangers, Marvin (author)This study discusses the potential of the in-depth water diversion (IDD) process to enhance oil recovery from subsurface reservoirs and investigates IDD strategies through an ensemble optimization approach. Pilot studies in the North Sea performed in recent years have shown that Sodium Silicate can be applied as blocking agent, diverting water...master thesis 2018

Murali, Vishal (author)The design of an offshore wind farm (OWF) is multidisciplinary in nature as it involves the design of many disciplines such as the wake effects, support structure, electrical cables etc. For the optimal design of an OWF, an optimization procedure is required where all the disciplines are optimized simultaneously. The objective function plays a...master thesis 2018

de Groot, Sjoerd (author)The goal of this thesis is to present a framework which can be used to optimize the observer and controller performance by placement of sensors and actuators on a continuous domain. The framework provides choices of model structure, cost functions and optimization methods to perform the placement. Systems which would be suitable for the use of...master thesis 2018

van den Bosch, Maarten (author)The development of the pole vaulting record is only improved by 1 centimeter over the last 25 years. Multiple studies show signs of different control strategies in elite pole vaulters, without pointing out what the cause of the differences is The aim of this research is to explore pole vaulting strategies by a control torque optimization. The...master thesis 2018

Vergeer, Michael (author)In the offshore industry, there is a growing demand for designing efficient, sustainable and competitive products. In order to fulfil the component requirements, a method named topology optimization can be applied. This is a mathematical design method which can be used in the early phases of the design process.At IHC there is an interest of...master thesis 2018

Chen, Yuan (author)The current situation with green gas emission requires the development of low carbon energy solutions. However, a significant part of the modern energy industry still relies on fossil fuels. To combine these two contradictory targets, we investigate a strategy based on a combination of CO2 sequestration with Enhanced Oil Recovery (EOR) in the...master thesis 2018
