During the design process of the new sea lock in IJmuiden the design wave conditions were described by a bimodal wave spectrum. With a spectral calculation method it was observed that a small low frequency component leaded to a large influence in the force spectrum. This observation served as the starting point for this thesis, where different...

Airfoil design plays an important role in improving the performance of Vertical Axis Wind Turbines(VAWTs). The aim of this thesis is to arrive at optimal airfoil geometries to enhance the performance of VAWTs and analyse the performance of these optimal airfoils under steady and unsteady operation conditions of the rotor. The airfoil design is...

Sediment nourishments have become an attractive alternative to hard measures in counteracting long-term river bed degradation. Due to the large degree of uncertainty concerning mixed sediment morphodynamics, river authorities conduct field studies to collect data that will help in the calibration of morphological models, eventually used to...

This research project aims at obtaining a better understanding of vertically translating the wing and the related wing-body interference effects on the drag and sonic boom. Computational Fluid Dynamics (CFD) analysis using the Euler equations has been used to evaluate an airplane with different vertical wing placements at a lift coefficient of 0...

With a rapidly growing population and subsequent technological developments, an increase in demand of rare-earth metals evolves. Land-based deposits seem to be insufficient and shortage impends within the coming decades. Mineral resources from the deep ocean are considered as a possible complement. These minerals occur in various forms. One of...

Differential vertical shortening (DVS) is the relative vertical shortening between two adjacent vertical load bearing elements. DVS originates because axial loading conditions on- and the design of adjacent vertical load bearing elements are different. Due to these differences, the reaction of the adjacent vertical structural elements expressed...

Offshore wind energy has very recently begun expanding into subarctic regions with seasonally ice-infested waters like the Baltic Sea. For offshore wind turbines with conventional support structures such as monopiles and jackets that are typically flexible and vertically sided, the phenomenon known as ice-induced vibrations can develop. In...

The growing importance of renewable energy to meet the demands of growing population has driven much focus for research in the wind energy sector. Currently most of the power production in the wind energy sector is done using the Horizontal Axis Wind Turbine (HAWT). due to its higher efficiency and reliability as compared to Vertical Axis Wind...

Over time, the width-averaged depth of estuaries changes due to a complex interaction of hydrodynamics and suspended sediment transport. In many estuaries one specic location with a suspended sediment concentration (SSC) higher than in the sea or in the upstream river, is found, which is called sediment
trapping. The location of the maximum...

The vertical tail size of a multi-engine aircraft is typically driven by the directional control requirement during one-engine-inoperative flight. This results in the vertical tail being over-sized for most regularly occurring flight conditions. By adding thrust vectoring technology to an aircraft, the vertical tail can be designed to cope with...

Composite steel-concrete floor systems consist of a trapezoidal shaped steel deck, reinforcement and cast-in-place concrete. Depending on the span, height restrictions and application shallow or deep decks can be chosen. The shallow deck used within this thesis is the ComFlor75. Due to the low self weight, a bundle of steel decks can be lifted...

The presence of vegetation has proven to increase peoples well-being and has multiple other benefits. Unfortunately, there is a lack of green in urban areas. Three solutions exist which could reintroduce green in cities and have a low footprint: green roofs, green facades and living wall system. Living wall systems are visible from street level...

Living wall systems are not applied on a large scale, even though they offer multiple benefits to buildings. They are able to improve the air quality, the insulation values or social and psychological benefits. The aim of this Thesis is to increase the application of living wall systems by designing a living wall system with the principles of...

An ever-increasing demand for electricity pushes the wind energy industry to deep waters that favor floating concepts. Vertical axis wind turbines (VAWTs) failed for onshore applications in the 1980s, but its advantages raise the potential for competitive floating designs and ultimately lowering the cost of energy. This thesis aims to (1) better...

In this research computational fluid dynamics (CFD) is used to model a vertical axis wind turbine. Well known turbulence models | i.e. the k-epsilon and k-omega SST model | are used and compared in their performance against each other and a set of experimental data. The formal research question is "What models are available for the simulation of...
