Abstract

The aerodynamic properties of a cricket ball largely depend on seams, surface roughness and the actions of the bowlers. Asymmetric airflow over the ball that is bowled fast, causes flight deviation (swing) and unpredictability in flight. Swing makes it difficult for a batsman to hit the ball and prevent getting bowled. Although some studies on swing have been conducted, the mechanism of reverse swing is not well understood. Hence the primary objective of this work was to understand the swing mechanisms affecting a cricket ball when bowled fast. The study is part of a larger research program including flow visualisation around a scaled cricket ball. A set of real cricket balls was also used to measure aerodynamic forces, using a six component force sensor in an industrial wind tunnel. These forces and moments were measured over a range of speeds and seam orientations.
