Enhanced oil recovery by gas injection can show excellent displacement efficiency but may suffer from poor sweep efficiency. A promising method to overcome poor sweep efficiency in gas-injection enhanced oil recovery processes is foam injection. The effect of oil saturation on foam stability is complicated and not fully understood. Complexity in...

Ocean thermal energy conversion (OTEC) is currently developed as a clean and sustainable energy technology for offshore application in tropical areas. The technology shows promising possibilities in combination with the Kalina cycle, a thermodynamic cycle for the generation of energy from low temperature difference heat sources using a working...

The modelling approaches can go to two extremes: fully data-oriented and fully process oriented. Modelling for diesel engines is not excluded. Usually data-oriented is computational friendly and accurate and the latter is detail and flexible. A high-speed diesel engine model is missing in project JOULES. The objective of this work is to develop...

Simulation of reservoir operations is important to investigate the effects of climate change and changes in human water demands on water availability in the future. Several reservoir simulation models exist, however it is unknown in which situations what type of model could be applied. This study tries to give an answer to the question how...

The port-Hamiltonian modelling and control of power converters has been the topic of a number of studies for the past couple years. However, the modelling of three-phase converters from fundamental port-Hamiltonian principles has been an unexplored direction. This study focusses on deducing a modelling procedure to model a three-phase rectifier...

The goals of this thesis were to understand the impact of uncertainties and modeling methods on the resulting stress and strain patterns and to see how 3D stress patterns can be linked to what was seen in the field. In 3 types of models simulations were done to carry out this goal. These are the 2D perturbation model, the 2D static model, and...

Unilever is the market leader in the fast moving consumer goods industry. It is constantlyseeking ways to effectively use its resources. The company approached me and requested a decision tool which could determine the 'switch-over' point between single and double stacking of pallets (the so-called stacking configuration). The model was to...

In the region of the Riau Islands of Indonesia fresh water scarcity is one of the challenges the local community is facing. In order to increase the catchment of fresh water the choice is made to turn Bintan Bay, part of the Riau Islands, into a fresh water reservoir. Hereby collecting the fresh water runoff from local rivers. It is however...

Offshore sand waves of several meters high and hundreds of meters long are formed in shallow seas due to the tidal currents. These sand waves can, amongst others, influence the burial depth of cables of offshore wind farms and obstruct navigation channels. For the Far Large Offshore Wind programme (FLOW), one of the goals of Deltares is to...

In this study a modelling approach was investigated that takes into account the effect of short wave grouping on long wave motions, calculating sediment transport and morphology with multiple fractions and a layered bed stratigraphy. After extensive testing and validating this model using data collected in a wave flume in Hannover this model was...

The interaction between vegetation and the morphodynamics is considered to be an important process in salt marsh formation and succession. Therefore, the contribution of vegetation modelling on the long-term morphological development of salt marshes is assessed by implementing a vegetation growth model in the morphodynamic modelling software...

Direct Internal Reforming (DIR) on Solid Oxide Fuel Cell (SOFC) anodes is often considered for fuel cells systems utilising carbon based fuels. Methane Steam Reforming (MSR) is one of the most extensively studied types of DIR. The hydrogen formed by the MSR reaction can be electrochemically oxidised in the fuel cell to produce electricity, while...

By its very nature dredging is an environmental impact, since dredging includes the excavation and/or relocation of sediment in a river, sea or estuary. One of the environmental impacts related to dredging is increased suspended sediment concentration (SSC) levels, forming plumes of sediment. These so called dredge plumes originate from spillage...

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

This master thesis comprehends a study on khettaras, historical subsurface drainage tunnels, in East Morocco. A numerical groundwater model was set up to simulate these systems and to get a better understanding of their behaviour. Subsequently, the model was used to simulate the effect of several scenarios: increased use of pumped wells in the...

Consequence of disturbance due to fault of earthing of on-board systems are not always clear. Second, the military EMC standards are outdated and the rationale behind these standards lacks. Therefore, research into rationale of standards and directives related to system earthing on board is necessary; in addition, develop appropriate on-board...

A common practice for hydrologists to determine the performance of a hydrological model and its parameter values, is by calibrating the model parameters on observed discharge data, but this data is not always available. For this reason, other data should be used as complementary data in order to reduce the uncertainty of outflow and processes in...

Current approaches that deliver energy insight to customers are rather poor, data centric and incomprehensible. Driven by the vision to differently support customers in the transition towards new energy behavior, the Energy Game was developed. This service aims to guide customers in their journey towards a situation in which customers manage...

Pathogens are present in our urban water system, and may pose a health risk to swimmers and playing children. Although the knowledge of pathogens has increased over recent years, little is known about their behaviour in the urban water system. The goal of this thesis is to investigate this. First, the behaviour of pathogens under the influence...
