With the increased use of Advanced Driver Assistance Systems (ADAS) in modern cars, the  field of surface contamination saw a resurgence. To keep the various sensors working properly it is of utmost importance to keep them clean and free of contamination. One way to achieve this is to ensure they are mounted in areas where they can be kept free...

This study explores the flowfield around a pusher propeller-wing configuration using Lagrangian Particle Tracking (LPT). It assesses LPT’s capability to characterise propeller-wing interactions, emphasising its ability to resolve complex flow dynamics.<br/><br/>The experiment successfully achieves high particle concentrations downstream of the...

Experimental aeroelasticity has been hindered by the intrusivity of measurement equipment and complexity of the experimental setups. Advancements in hardware development have been encouraging optical tracking techniques to replace cross correlation approaches in experimental aerodynamics. However, digital image correlation (DIC) is still the...

This thesis presents a novel measurement approach for aeroelastic wind tunnel testing. The key novelty of this approach is the integrated measurement of aerodynamic and structural quantities using an optical technique. The considered approach consists of combined measurements of flow tracer particles and structural markers using a Lagrangian...

The Atlantic Meridional Overturning Circulation (AMOC) is an important element in the Earth’s Climate System, and it leads to variations in the climate systems, such as heat transformation, carbon dioxide distribution, freshwater distribution, and extreme weather conditions. <br/>The dense water formation and export in the North Atlantic...

Mangrove forests are important (sub)tropical intertidal ecosystems providing coastal protection and other ecosystem services like carbon storage and biodiversity. In view of the loss of these forests many rehabilitation projects have started, but unfortunately these efforts often fail. A main cause for coastal erosion is a disrupted (fine)...

The aeroelastic response of a highly flexible wing to periodic gust excitation is determined experimentally. The integrated optical measurement approach that is applied provides combined measurements of the structural response of the wing and the unsteady flow field around it. The aeroelastic loads acting on the wing are derived from these...

Three-dimensional Lagrangian particle tracking measurements with helium filled soap bubbles provide quantitative flow visualizations in large measurement volumes up to the cubic metre scale. However, the instantaneously available fluid information density is severely restricted by the finite spatial resolution of the measurements. Therefore,...

The Labrador Sea is one of the deep convection sites in the world's oceans and the water masses formed here are an important component of the Atlantic Meridional Overturning Circulation (AMOC). To study this linkage, one study in particular used an idealized model of the Labrador Sea where the density variations consists only of temperature...

The gradually increasing air pollution calls for more and more effective solutions. This master thesis is focused on the investigation of aerosol trajectories inside the agricultural purifier named `ASPRA Agro', developed at VFA Solutions. Various CFD simulations have been carried out using an open-source C++ toolbox named `OpenFOAM'. The flow...

Car industry and motorsport development nowadays strongly rely on wind tunnel testing. As the literature survey shows, in order to fully understand the characteristics of the flow around a car, large-scale and volumetric flow field measurements are required. For its features, PIV can be pointed as a useful technique for automotive wind tunnels....

A new approach is introduced to evaluate the potential drag reduction by skin suit design in speed sport. The approach relies upon local flow information measured in the wake of a cyclist mannequin. Lagrangian Particle Tracking is employed to measure the distribution of time-average streamwise velocity in a cross-plane of 30 × 100 cm2 behind the...

Aerodynamics research and development often involves large-scale and turbulent flows; may this be a rotor flow, the wake of a car, or the flow passing a human athlete to name a few examples. Volumetric particle image velocimetry (PIV) is well suited for the study of such flows. The introduction of Helium Filled Soap Bubbles (HFSB) for wind...

We present results from two large-volume volumetric flow experiments. The first of these, investigating a thermal plume at low velocities (up to 0.35 m/s) demonstrates the abilities and requirements to reach volume sizes up to and probably beyond one cubic meter. It is shown that the use of Helium filled soap bubbles (HFSBs) as tracers, combined...
