Energy demand from wind greatly increases, as such more remote sites need to be explored in order to find good wind resources. These remote sites are driving the industry further offshore and therefore into extreme wind and sea conditions. This push towards extreme conditions requires technological advancements concerning the wind turbine loads,...

In this thesis the goal is to grow the fundamental understanding of the Shrink Sleeve Labeling process, speciffically on the steam tunnel equipment. The research is focused on the heat transfer phenomena of the ow on to the bottle. From literature was found that the problem could be split into 3 general domains: 1) free jet ow, 2) heat transfer...

The need for energy is an ever increasing problem and most resources that are used today will be exhausted or no longer tolerated by the human kind in the future Omer (2008). Anticipating on the energy demand the development of wind turbines has taken a big leap and to improve the design process efficient and accurate aerodynamic modelling is...

Micro-ramps are currently being investigated as a means of reducing negative effects of shock wave-turbulent boundary layer interactions. A micro-ramp enhances the mixing of the ow by introducing vortices in the ow, thus energizing the boundary layer to overcome the adverse pressure gradient due to an impinging shock. The effect of changing...

This study is aimed at modelling of the unsteady interacting boundary layer around wind turbine rotor blades. It is shown that nonconservative mechanisms are present in this system, affecting the definition and approximation of solutions to the problem. The objective is to overcome the inconsistency of classical (dissipative) schemes, and find a...

This thesis demonstrated how the Newton and BFGS algorithm could be used to solve the standard VGM relations and least-squares formulation respectively, for arbitrary forms of the _ parameter, including nonlinear _ s, appearing in the VMM. The proposed procedure were also shown to be able to handle arbitrary projectors that are compatible with...

Scientists and engineers use observations, mathematical and computational models to predict the behaviour of physical realities such as turbulent ows. However, as a consequence of observational errors, errors in the mathematical models and discretisation errors in the computational models, our knowledge about what happens in reality is imperfect...

This thesis aims to explore and enable parameter estimation using the data assimilation method of the ensemble Kalman filter (EnKF). More specillically applied to the quasi-steady flow field, measured using particle image velocimetry (PIV), of a plasma actuator in quiescent ow where the parameters to be estimated are those describing the force...

This study investigated the effect of chord deformation on the unsteady aerodynamic mechanisms found in hovering flapping flight at a Reynolds number of Re = 2002. This was done in order to get a better understanding of the physics involved in flapping flight, which in turn could lead to improved Micro Aerial Vehicle (MAV) designs. A three...

In the present thesis report the author synthetizes 9 months of work at the DSNA department of ONERA in Chatillon, France. The topic of the thesis is goal oriented mesh adaptation with particular application to unstructured grids and to _nite volume methods. The motivation of the present work is the application to unstructured meshes of a novel...

The computational modelling of fluid-structure interaction phenomena is currently gaining importance thanks to engineering design trends towards lighter and more exible structures. FSI simulations are important because they can predict potentially dangerous interaction instabilities and the performance of designs in their deformed shapes....

The goal of the thesis was to establish and validate a model for maneuvering fruit fly flight. Fruit flies are capable of rapidly changing direction and accelerating away from a threat during so-called escape maneuvers. The maneuverability and control of these escape maneuvers are of interest for the development of small unmanned aircraft (Micro...

One of the main limitations of microphone measurements in an open-jet wind tunnel is spectral broadening. The phenomenon of spectral broadening is observed when a single frequency sound wave passes through a free shear layer. Inside the turbulent shear layer the wave interacts with the turbulence, which leads to broadening of the tone in the...

The continuous increase in fuel prices and stricter regulations on emissions have pushed the attention of truck designers into new areas to provide more fuel effcient solutions. The flow in the front wheelhouse is a relatively unexplored area, compared to studies on the shapes of the cabin, roof and trailer. However, it is known that the...

This report discusses the potential of pylon trailing edge blowing to reduce the adverse effects of airframe installation on the performance and noise emissions of pusher propellers. Both experimental and numerical analyses were performed, focusing on the pylon wake profiles, the propeller performance, and the propeller noise emissions. The...

Active load control for load alleviation has become more important in the wind energy industry in recent years. The continuously increasing size of wind turbines has eventually led to the point where efficient mitigation of the fatigue loads on the blades, due to unsteady wind or gusts, is becoming an important aspect in the design. Suppression...

Because of the low fuel consumption, turboprop aircraft have made a strong revival during recent years and have come to dominate the current regional flight market. Increased interest in propeller research is a result of this trend. This thesis project focuses on the effect of non-uniform inflow on the propeller performance. Two sources of non...

Understanding, predicting and controlling laminar to turbulent transition is of great interest due to the wide range of practical applications where transition is significant. Generally, turbulent flow has an order of magnitude higher skin friction. Fuel savings of up to 25% would be possible for a large commercial aircraft if laminar flow could...

Amidst the growing demand for energy, many nations are considering the expanded role of nuclear power in their energy portfolios. However, in case of severe accidents, large amounts of hydrogen gas can be released in the nuclear containment. Hydrogen-air mixture forms a very ammable gas which on subsequent ignition can lead to ame propagation in...
