Increasing demand for oil in the near future implies the need for Enhanced Oil Recovery (EOR) methods to produce the remaining oil after primary and secondary production. Miscible gas injection has an excellent microscopic sweep efficiency; however due to density difference, high gas mobility and reservoir heterogeneity, the macroscopic sweep...

In the research on solar cells, accurate characterization techniques are of great importance. In this work a specific technique is studied that makes use of transmitted and reflected light from a thin layer. The material properties of transparent conductive oxides (TCOs), silicon and nanoparticles are extracted by fitting a mathematical model on...

Shells are thin-walled curved structures that have great potential for multistability. However, there does not yet exist a general model that can be used to predict the stable equilibria of an arbitrary shell; this model would have to capture the complex interplay of (initial) geometry, material parameters and (local) prestress. In this thesis...

Currently, morphodynamic models as XBeach show substantial overestimations of the erosion rates during breaching and overwash events at barrier islands. The presently used limitations on the Shields parameter and the sediment concentration do hinder erosion, but have undesirable side effects, e.g. the breaching process is suppressed. By...

Carbon dioxide (CO2) is one of the main greenhouse gases that contributes to the current climate change. Its increasing share in the Earth atmosphere leads to an increase in global temperature. To prevent the sea level from rising and increased severity of extreme weather, many governments are now trying to reduce their carbon footprint. One...

Mixing systems are used in deep lakes to prevent blue algae from rapidly growing. Air bubbles rise from the bed, dragging water from below upwards. The resulting vertical circulation suppresses blue algae growth. However, these systems demand electricity of about €25,000 per km2 per year. The airlift promises to mix the water more efficiently,...

THE aviation industry is responsible for 12% of the total transportation impact of CO2 while awareness, for decreasing the total carbon footprint, is rising. Both the aerospace and the automotive industry are facing an increasing pressure from society to make the transportation sector more sustainable. Within the automotive industry slowly an...

A conventional annealing line uses a gas fired or electrical heating to heat and gas jets to cool the steel strip. The energy supplied during heating is lost in the cooling section. This energy has a lot of potential which can be recovered and used for the heating of the cold steel strip. Tata Steel, TU Delft and Drever International are...

Multivariate simplex B-splines as a modelling technique provide more accurate models than standard polynomial models, which makes them an excellent modelling tool. Their coefficients, which are expressed in a barycentric coordinate system, are abstract. In this paper a physical transformation matrix is derived which can be applied to transform B...

Areas are getting more and more populated causing new infrastructure lines to be constructed below the surface. A bored tunnel is one of the possibilities to create this subsurface infrastructure, but the construction process of a bored tunnel is a complicated one. Many loads and aspects are present in this construction process that can be...

Prediction of emissions from combustion systems is a complex problem involving the coupling between the flow field and chemistry. CFD analysis is the most commonly employed approach. However, it has the drawback that a very high computational cost prevents the use of detailed chemistry models. This master thesis, which focuses on NOx emissions,...

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...

Helicopters are complex and expensive aircraft with a level of technology that is immature compared to fixed- wing counterparts. Helicopters suffer from vibratory loads stemming from the main rotor and exhibit control and stability problems in the low-speed flight regime. Operating a helicopter near the limits of its flight envelope may result...

Information Technology [IT] is increasingly being integrated into the modern society. Novel IT solutions are Cloud based. Cloud solutions from Microsoft Azure and Amazon AWS are examples of services which offer the benefits of cloud computing. For IT providers, leveraging novel IT artefacts may require the development of a new service model. IT...

The industrial site of Vosdonk Noord at Etten-Leur in the Netherlands consists of a large soil contamination in combination with highly heterogenic shallow subsurface soil characteristics. In this report, we study the groundwater flow and solute transport behaviour at this project location. Throughout this process, knowledge is gathered about...

Eddy currents are loops of electrical currents induced within conductors by varying magnetic field in the conductor. Eddy currents flow in the closed loops in the conductor, in planes perpendicular to the magnetic field. The eddy current effect plays an important role in the transformer or an actuator system. <br/>If there is a coil wound around...

The COBRAcable project is one of the major interconnectors being constructed in the North Sea, connecting the Netherlands with Denmark. It is a 325 km submarine cable which will have the ability to transfer 700 MW. The importance of the interconnector is manifold: to facilitate the exchange of renewable energy coming from the onshore Danish...

Many robotic systems rely on laser ranging sensors to navigate and map their environment. As robots are getting more advanced, smaller and cheaper, their sensors need to decrease in size and cost, while increasing their reliability and accuracy. Current laser-based sensors have difficulty to meet these properties. They are either large,...

Transitioning to cleaner sources of energy and improving the efficiency of power generators are crucial in combating global warming. Organic Rankine Cycles (ORC) when coupled to heat emitting power generators allows for waste heat recovery; thus increasing the engine overall efficiency and reducing atmospheric pollution. Additionally,...
