Velocity measurements within the core of high-swirl vortices are often hampered by heavier-than-air particle tracers being centrifuged outside the vortex core region. The use of neutrally buoyant and lighter-than-air tracers is investigated to aim at homogeneous tracers concentration in air flow experiments dealing with high-swirl vortices...

For μCHP applications, micro gas turbines offer many potential advantages in comparison to other conver- sion technologies due to their compact size and high specific power, low vibration and noise, low mainte- nance requirements, low emissions and high-grade residual thermal energy. Optimisation of MTT compressor with a vaneless diffuser (OCVLD...

The mechanism of three-dimensional shock control bumps (SCBs) to reduce wave drag is widely understood. Further, it has been claimed potential for passive flow control of transonic buffet. Although the underlying mechanisms of how SCBs favourably influence buffet onset are thought to be understood in broad terms, no experiments of SCBs in an...

A method is introduced to measure the aerodynamic drag of moving objects such as ground vehicles or athletes in speed sports. Experiments are conducted as proof-of-concept that yield the aerodynamic drag of a sphere towed through a square duct in stagnant air. The drag force is evaluated using large-scale tomographic PIV and invoking the time...

Turbidity currents are an essential agent of sediment transport from shallow to deeper waters. Detailed measurements of the velocity field or particle concentration are only available by means of accurate numerical simulations. In this thesis, a DNS solver for turbidity currents is presented based on the MEEVC scheme, a mass, energy, enstrophy...

Monitoring and optimising turbine performance are important tasks of a wind energy operator. However, monitoring activities are expensive and the current state-of-the-art in this field could be improved. A newly developed Avent five-beam Lidar was tested and the impact of heterogeneity on Lidar measurements was analysed. Also, the effect of...

Blended wing body aircraft represent a paradigm shift in jet transport aircraft design. Stepping away from the conventional tube-and-wing philosophy, they promise benefits over existing or future conventional aircraft. The most significant challenge with the concept is the increased coupling between aircraft design disciplines that has...

From Particle Image Velocimetry data, pressure and velocity fields are reconstructed using mimetic isogeometric analysis. This technique allows for high order divergence free reconstructions on complex CAD geometry, and automatic filtering of noise in the data. Noise filtering performance is investigated using a Monte-Carlo simulation. The...

The introduction of metal into the aeronautical industry made the wings and aerostructures stiff and rigid. High-lift devices and movable surfaces allow for discrete deflections to increase lift coefficient and control of the aircraft. Several researchers have proposed concepts for variable camber, allowing continuous deflections. This is...

Air traffic is expected to grow over the next few decades, which will cause the global fuel consumption to increase. Reducing the drag of an aircraft will result in a reduction of the fuel consumption. Non-planar configurations may offer a solution to reduce the drag while maintaining the performance of today’s aircraft. The aim of this study is...

The importance of reliable and efficient launch vehicles pervades the many industries which rely on space based hardware. An experimental investigation has been performed into the effects of nozzle length and exhaust plume presence on a FESTIP axisymmetric base flow at Mach 0.7. Three different nozzle lengths (L/D = 0.6, 1.2, 1.8) were tested to...

In the automotive industry the development process is driven by a highly competitive market, calling for shorter and more cost-efficient development procedures. Computer aided engineering (CAE) is one possibility to achieve these reductions and becomes an inevitable tool in the development process. However, CAE does not provide the subjective...
