A wall-resolved Large Eddy Simulation (LES) of a wing-body junction is performed. The aim is to generate high-fidelity junction flow data to be used in a data-driven turbulence modelling approach, specifically to improve the accuracy of RANS-simulations in junction flows. The simulation is performed on a 61.5 million C-grid body fitted mesh in...

The increasing importance of climate change and stricter regulations for greenhouse gas emissions raise the pressure on the automotive industry to develop more efficient products. Besides a reduction of emissions by new combustion engines, electric vehicles are being introduced to lower the fleet fuel economy. Especially this new drivetrain...

Dimples are shallow, indented surfaces that attempt to reduce drag in turbulent boundary layer flows. However, the underlying effect of the dimples on the drag is not entirely understood. This thesis sets out to expand our understanding; a numerical investigation of turbulent boundary layer flow over dimpled surfaces is conducted. This research...

There is a tremendous push to explore alternative fuels such as hydrogen or synthetic fuels to combat the effects of climate change. An important step in the development of alternative fuels is the characterisation of its combustion characteristics. There are various diagnostic tools which aid in the determination of flame properties. Optical...

Multi-agent robotic systems could benefit from reinforcement learning algorithms that are able to learn behaviours in a small number trials, a property known as sample efficiency. This research investigates the use of learned world models to create more sample-efficient algorithms. We present a novel multi-agent model-based reinforcement...

The buildup phase at KLM Cargo requires cumbersome planning actions because of a slow data handover at the warehouse and an uncertain initial state of the buildup process at the beginning of the shift. This study presents a model to improve scheduling of future buildup shifts according to flight departure times of KLM. The most important...

Commercial FSI solvers employ partitioned FSI, wherein CFD and CSM solvers are used sequentially to resolve the coupling of interface displacement and stress/force. For strongly coupled problems, multiple sub-iterations of both the solvers are required for a stable and accurate solution. IQN-ILS framework requires fewer sub-iterations for...

The environmental impact of aviation is a well-known issue scientists all around the world are desperate to tackle. The population that can afford air travel is growing and this demand is likely to double within the next 20 years. This increasing demand comes at a hefty price: the emissions of greenhouse gases cause climate change and local air...

Aviation has experienced a huge leap in technology since the Wright Brothers first took flight in 1903. From the first propeller powered wood and canvas aircraft to the modern day aluminium and carbon fibre reinforced plastics jet aircraft [33], aviation has evolved. Next to the evolution of materials and aircraft going from propeller to high...

Saturn's largest natural satellite, Titan, is an icy moon expected to harbour a liquid sub-surface water ocean capable of habiting extra-terrestrial life. The spherical harmonic expansion of the gravity field and the tidal Love number k2 can be used to estimate densities, depths, and phases of different layers from Titan’s interior structure,...

Planetary observational accuracy increases and the dynamical modeling of tidal behaviour has to follow. In this thesis, a newly developed method (Correia et al. 2014; Boue et al. 2016) to deal with tidal interactions in a 2D two body problem is validated and for the first time applied to Solar system dynamics on a short time-scale. This method...

Various machine learning algorithms have been applied to find optimal lowthrust<br/>satellite trajectories, however, no fair comparison of their accuracy has been made yet. In this paper, two common and promising supervised machine learning algorithms are compared for their regression capacities:<br/>the artificial neural network and the...

In order to assess the span-wise load distribution in an aeroelastic gust encounter, a novel method is developed which makes use of marker-based optical tracking. This allows for the prediction of the elastic force and the computation of the inertial force such that Collar's triangle may be quantified during the encounter through an iFEM...

In recent efforts to improve the theory of human control behaviour, different system identification techniques have been developed to estimate human linear time-invariant feedback- and feedforward control behavior. This thesis focuses on a newly developed subsystem identification (SSID) technique, that estimates feedback- and feedforward...

Traditional fuel system designs do not provide the combination of sucient cooling and low system weight at the Mach 5+ range. Thus, if currently available non-cryogenic propellants are to be employed, an additional heat sink source beyond a simple physical heat sink is required to meet the regenerative cooling demand. The endothermic...

The aerospace industry increasingly uses fibre-reinforced plastics that are manufactured using automated fibre placement (AFP). A common problem in AFP is the occurrence of gaps and overlaps that affect the structural perfromance of laminates. Tow width fluctuation is an important cause of gaps and overlaps. Two developments in manufacturing are...

By 2030, a new amphibious transport ship is to be available for the Dutch Royal Navy. In light of the foreseen rise in airborne operations from the ship, more insight is desired into the impact of ship design choices on helicopter operational availability. There is need for a predictive tool, which can be used in the early design phase of the...

Even though hundreds of CubeSats have been launched, few have launched with a micropropulsion module on board. Propulsion would allow for an extended lifetime and better mission capabilities, thus greatly increasing the attractiveness of CubeSats. TU Delft is working on a type of thruster suitable for CubeSats, called the Vaporizing Liquid...

The combination of a relatively recent emissions scandal and the ever growing incentive to provide sustainable transportation solutions, led to the fact that the transition to electrically propelled land-based vehicles is more prominent than ever. All prominent European car-makers announced diverse fully and partially electric product portfolios...

In 1995 the Galileo spacecraft arrived at the Jovian system and performed a first flyby with Io to decrease the required $\Delta V$ for orbit insertion. This technique is generally known as "satellite-aided planetary capture". The thesis research combines low-radiation satellite-aided capture trajectories with low-thrust propulsion and sees what...
