The mystery of cricket ball swing has fascinated the bowlers and batsmen as well as spectators and cricket critiques from the very first appearance of the game. This nonlinear flight is mainly due to the aerodynamic properties of the cricket ball which has been investigated by many researchers in the last three decades. While conducting a lot of experimental studies, their main interest was to figuring out the factors and conditions affecting the swing. However, a lot of features responsible for both conventional and reverse swing are yet to be known. In this study, rather than performing experimental study, a computational approach is undertaken to investigate the effects of different parameters on the swing of the cricket ball. The newly developed and widely used CFD (Computational Fluid Dynamics) tools and their commercial packages have been applied in this study and the effect of seam angle, bowling speed and surface roughness are considered. This study explains the conventional swing and finds out the critical combination of the above parameters to produce reverse swing with an old ball.
