Investigation of Footballs Wakes by Robotic Volumetric PIV

The robotic volumetric PIV system of the TU Delft is proposed to be used to gather quantitative data in the wakes of footballs. For over a decade now, a new football is introduced every FIFA World Cup. The varying surface characteristics affect the behaviour of the footballs in flight, and so football aerodynamics has become subject to increased...

Bridging PIV spatial and temporal resolution using governing equations and development of the coaxial volumetric velocimeter

A series of techniques is proposed for volumetric air flow measurements that are based upon the principles of particle image velocimetry (PIV). The proposed techniques fall in two categories; part 1 of this dissertation considers measurement data processing using constitutive laws and part 2 focuses on development of a coaxial volumetric flow...
