Pollution dispersion from highways: Enhancing particulate matter capture using aerodynamics

People living or working close to the highways are at risk to higher exposure levels of different air pollutants, one of which is particulate matter. The Antea group has recently proposed the addition of Electrostatic Precipitators (or ESPs) on the top of sound barriers adjacent to highways, in order to capture the particulate matter and safely...

Impact of Turning Induced Shape Deformations on Aerodynamic Performance of Leading Edge Inflatable Kites: Master Thesis

With growing energy demands and a need to switch to a sustainable source of energy key stakeholders are considering the use of high altitude wind energy systems. TU Delft and its start up company kitepower are key stakeholders investigating the commercial viability of this technology. With this goal the research group has developed several kite...

Double actuator cylinder (AC) model of a tandem vertical axis wind turbine (VAWT) counter-rotating rotor concept operating in different wind conditions

The aim of this thesis is to evaluate the influence between the two counter-rotating VAWT rotors with the Double Actuator Cylinder (DAC) model which will be validated against the panel code. The DAC model is developed from the original Actuator Cylinder (AC) model which includes the Modified-Linear (Mod-Lin) correction. The original AC model for...

Robotic Volumetric Particle Tracking Velocimetry by Coaxial Imaging and Illumination

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...

Unsteady Pylon Loading for Pylon-Mounted Tractor Propellers

Air-Wake Flow Dynamics on a Simplified Frigate Shape: An Experimental Study by Large-Scale Tomographic PTV

: The Air-Wake produced by a ship superstructure is a complex, highly turbulent and unsteady three-dimensional flow, which contains large flow features that interact with the helicopter rotor during critical take-off and landing procedures. An international research effort (TTCP, AER-TP2) which involves experimental and numerical studies on...

Hybrid Eulerian-Lagrangian Vortex Particle Method: A fast and accurate numerical method for 2D Vertical-Axis Wind Turbine

The wake geometry of a Vertical Axis Wind Turbine (VAWT) is unlike the standard Horizontal Axis Wind Turbine (HAWT). The blades of the turbine continuously passes through its own wake, creating complex wake-body interactions such as flow separation and dynamic stall, and convectional grid-based numerical method which is capable of describing...

Optimal Team Time Trial Strategy in Road Cycling: Optimisation of Changing Strategy using a Mathematical Performance model

During team time trials in road cycling changing schemes are used to spread the workload over the cyclists in the team. Models that provide predictions of race performance already exist for individual time trials. It is proposed that with a performance model for team time trials, the performance of different strategies can be compared and...

Development of a KBE application to support aerodynamic design and analysis: Towards a next-generation multi-model generator

The aviation industry faces a number of challenges: it needs to produce safer, quieter and more efficient aircraft to meet the demands of the airlines and increasingly strict regulations. At the same time, engineers are becoming more scarce because the retirement age of the `baby-boom generation' is approaching. The department of Systems...
