A proportionate controller is investigated experimentally for unsteady load alleviation purposes on a 2D wing model with a trailing edge flap. This study is supposed to be a simplified version of a Smart Rotor, a mechanism which deals with the reduction of unsteady loads acting on a wind turbine and aims to understand the behavior of this type...

Recall that the first aim of this thesis was to assess whether we can derive bi-orthogonality relations demonstrating that the adjoint LST eigenvectors are orthogonal to the direct eigenvectors, for both the compressible and incompressible LST equations; thereby resolving the non-orthogonality complication. It is to that end that we derived the...

Recent decades, an ongoing trend has emerged in the upscaling of wind turbines in order to compete with traditional energy resources. For conventional wind turbines, aside from improving safety, the driving factors for new designs have always been increased efficiency and performance. This has led to novel wind turbine designs comprising thin...

Transonic buffet is an aerodynamic instability that appears on aerofoils and wings at certain combinations of Mach number and angle of attack, and which limits the aircraft flight envelope. This thesis project presents an experimental<br/>investigation of buffet employing stereoscopic PIV and Background Oriented Schlieren. By using four...

Stall is traditionally divided in three types of stall behaviour, these have been regarded as two dimensional and dominated by the airfoil shape. However one of these types of stall behaviour, trailing edge stall, has been shown in literature to be three dimensional by forming stall cells along the wing span. Stall cells are coherent flow...

An experimental investigation on shock-shock interactions has been conducted with the aim of studying the transition between Regular (RI) and Mach interactions (MI) under the condition of variable inflow Mach number. The RI contains only oblique shocks while the MI has a quasi-normal shock segment, known as the Mach stem. MI configurations...

The aim of this investigation is to provide an experimental volumetric visualization of the near wake topology of the vortex structures generated by a flapping-wing Micro Air Vehicle (MAV) by means of large-scale Robotic PIV. This novel technique implements coaxial illumination and imaging in combination with the use of Helium Filled Soap...

Flapping wings display complex flows which can be used to generate large lift forces. Flexibility in wings is widely used by natural flyers to increase the aerodynamic performance. The influence of wing flexibility on the flow can be computed using numerical analysis with Fluid Structure Interaction (FSI). However, there is a lack of open-source...

Bird flight has evolved to be highly efficient over a time span of a million years. Much of the evolution in flight of various birds is specialized to increase the flight performance of the bird in the adopted habitat. The bird flight in a macroscopic point of view has been a topic of research for a long time now. A few researchers in the past...

During the launching vehicles design and their optimization process, the implementing of aerodynamic characteristics (AC) database is quite important. Accuracy of such database determines quality of the pre-flight simulation, trajectory and even the whole design direction. However, the database building process is one of the most challenging...

How hawk moths and many other flying insects acquire information on body rotations outside of the visual system is still unknown. Vision is important for flight stability, but generally believed to be too slow to explain fast reflexes during maneuvers and hovering for species such as the Manduca sexta. Insects in the Diptera order (the true...

The drag characteristics and flows structures over flat surfaces with a pattern of shallow rounded spherical dimples were studied. Such dimpled surfaces have been investigated by a small number of researchers in the past, which have shown a potential for drag reduction of a flat plate in a turbulent boundary layer [Kiknadze et al. (2013)]. These...

After the invention of the rocket mankind saw a new possibility to study the universe and other planets than Earth by space travel. Since then man has achieved to orbit Earth, land on the Moon and Mars. The constant increase in the demands of future space exploration mission make that also the equipment needs to be _t to the task. For example in...

This abstract describes the research performed to predict the wall temperature distribution on the door of a target-type thrust reverser by means of coupled aero-thermal simulations. The research is performed to obtain the degree of Master of Science in Aerospace Engineering from the Technical University of Delft. The project is carried out at...

Junction flows occur when a boundary layer encounters an obstacle (such as a wing) on its path. They can occurr either in laminar or turbulent flow conditions but only the turbulent case is considered here. This type of flow is usually a 3D, anistoropic, unsteady, turbulent flow. These characteristics are the result of two main phenomena. The...

Shock Wave Boundary Layer Interactions (SWBLIs) occur frequently in supersonic and hypersonic flows and, depending on the strength of the shock wave and the state of the boundary layer, may lead to boundary layer separation. This can result in a multitude of problems, such as an increase in drag, a drop in air intake efficiency and high fatigue...

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...
