Abstract

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 investigation, but little quantitative data has been collected of the wake flow until now. The proposed system could potentially be used in the future to aid design/certification of new footballs. To prove the system is suitable, it was used to take measurements in the wakes of footballs in wind tunnel tests. Although the system itself was proven suitable, an issue concerning fixating the footballs arose and it is essential this is solved for the system to have relevance. Recommendations for future work to tackle this are proposed.
