Development of robotic volumetric PIV: with applications in sports aerodynamics

Particle image velocimetry (PIV) is the state of the art for quantitative, full-field, 3D flow diagnostics. Despite the maturity of the technique, two bottlenecks are identified which are addressed in this thesis: the achievable measurement volume size, and the optical access to geometrically complex objects. Both aspects are well illustrated...

Submerged Supersonic Intakes: An experimental investigation by means of PIV, Schlieren and pressure measurements

Supersonic intakes are essential in assuring proper combustion for operating ramjet engines on cruise missiles. However, due to increasing threats and a rapidly changing service environment, today's intakes do not fit anymore to comply with the new set of requirements to tackle the above challenges. Therefore, a novel supersonic intake design is...

Surface Pressure Measurements using Coaxial Volumetric Velocimetry: Investigation on an Inverted Wing in Ground Effect

In experimental aerodynamics, pressure is an important parameter which provides insight into the various features of the flow around the test object. By obtaining the surface pressure information, various inferences can be drawn such as flow separation, local flow velocity etc. Traditionally, the most common method of obtaining pressure has been...

Time-averaged pressure from Robotic Volumetric PIV

Pressure represents a physical magnitude which allows the characterisation of flow behaviour. Its study is<br/>of great interest for engineering purposes and is broadly reported in the literature. The practical implementation of pressure measurements in industrial wind tunnel facilities involves the use of intrusive pressure probes only able to...
