A low-speed aerodynamic analysis on the conventional NACA ram-air inlet of the Airbus A320 with a new closure flap was conducted. The conventional closure flap mechanism inside the NACA ram-air inlet is replaced by a morphing plate design. Steady-state Reynolds-Averaged Navier-Stokes (RANS) based Computational Fluid Dynamics (CFD) simulations...

Soil Moisture is a key hydrological variable since it controls the interactions between the atmosphere, biosphere and hydrosphere. It is responsible for the partitioning of precipitation into evaporation, transpiration, percolation and run-off. Soil Moisture monitoring is used to indicate droughts in vegetated areas and is an important parameter...

This thesis introduces a fragility-based framework in order to perform a custom assessment of the complex Eastern Scheldt storm surge barrier. By applying a conditional approach to loading parameters, the statistical dependency between failure mechanisms and structure elements can be described separately for the strength and loading part of the...

Constructing a dam across a tidal basin has alway been a long-term integral solution to many water related problems of the surrounding area such as flooding, river control and fresh water storage. However, immense challenges are accompanied with the closure works of large basins. This research treats the closure strategy to close the Gulf of...

When it comes to mobile devices, off-boarding is a less well-acknowledged part of the product lifecycle, the vocabularies around endings are deficient. Both consumers and companies, however, tend to overlook the importance of the EOU consumer experience and its impact on a transition towards a CE. Companies like to introduce ‘hello’ to new...

Hydrothermal flames have become a very important field of study, especially for supercritical water oxidation. In supercritical water oxidation hazardous, toxic or non-biodegradable aqueous organic waste water streams can be efficiently destructed. Supercritical water oxidation takes place in a aqueous environment above the supercritical point....

Tidal basins are highly dynamic environments with a complex behavior that is often disturbed by human activities. Considering that tidal dynamics have a direct impact on surrounding engineering infrastructures, adjacent coastlines, nature environment and socio-economic human activities, it is crucial to know the impact of human interventions on...

The dynamic nature of braided rivers can lead to river bank erosion, bankline shifts and navigational hindrance. River training measures can be implemented in order to mitigate these problems. An alternative to conventional river training works is the closure of a channel within the braided network. Until recent there has been no systematic...

In large braided rivers, river training is often required to protect the banks against erosion, to improve navigability and for land reclamation. Closing one of the channels is a promising option to achieve these goals. However, there is a lack of systematic research on channel closures and no guidelines for their use exist. In the few...

Dams are an essential part of the Dutch flood defence works to protect the hinterland from flooding by the sea. Sand closures are the construction of closure dams with sand as the main building material. The rising and falling tide generates a current through the closure gap, which increases in strength as the gap becomes smaller. This current...

A parametric finite element model incorporating virtual crack closure technique was developed in order to determine the critical disbond size and location for disbond growth in an adhesively bonded skin stiffened structure, subjected to uniaxial compression loading. The model was validated using static experimental tests on both pristine and...

Conventional theories to describe and predict FCG are based on a SIF parameter, ΔK. If ΔK is used as similitude parameter to predict FCG, an R-effect arises. This R-effect can be accounted for by means of plasticity induced crack closure: A plastic wake behind the crack tip causes the crack to close before a zero tensile load is applied. As such...

Fulfilling our energy demands with renewable resources is one of the world’s greatest current challenges. Building offshore wind farms and using wind energy is one option to achieve this goal. The cost efficiency of offshore wind farms is still limited however, due to high construction and maintenance costs. Several research and development...

Tidal inlet systems are found all over the world. These highly dynamic coastal features can be classified into three main types wave-dominated, tide-dominated or river-dominated tidal inlet systems. A tidal inlet is described as an opening in the shoreline that provides a connection between the ocean and a bay and is maintained by tidal currents...

Smart Home, or the automation of home and household activity, has been believed to be the home of future. It makes the operation of home apparatus much easier, more flexible and comfortable by enabling control at a certain range of distance, time and magnitude. After decades of gradual development, this domain is recently experiencing a rapid...

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...

A skin lesion is an abnormal tissue formation on the skin, examples are skin cancers and nevi (moles and birthmarks). Every day, thousands of people have a skin lesion removed, for a number of different reasons. The lesion could be malignant (like skin cancers), show a risk of malignancy or removal could be for cosmetic or practical reasons. The...

Floods cause, even in modern countries, a lot of victims and damage every year. Generally, countries invest in prevention and protection, yet, also emergency response measures could be a (last) option. Regarding the latter, a distinction is made between preventive emergency measures (e.g. sand bags to raise the crest level of a flood defence)...

At the construction of 'Maasvlakte 2' in 2012, two sand closures were constructed. Sand is in most cases the most profiting construction material. The processes and the amount of sand losses which occur during the construction of a closure contain large uncertainties. In order to construct a closure, the production of sand has to be larger than...

With the development of a process-based model (Delft3D) of the St Lucia Estuary inlet, a first approach is made with regard to the estuary mouth dynamics and closure mechanisms that are observed at St Lucia inlet. The purpose of this thesis is to get a better understanding of the hydrodynamic and morphological behaviour of the St Lucia inlet...
