Abstract

Cricket balls behave differently at various stages of the game depending upon how much wear and tear has taken place due to use. The playing performance of cricket balls depends largely on the surface texture. The ball is swung using the primary seam during the early stages of the game but later the surface roughness starts to affect the lateral movement. This work attempts to find a quantitative measure of the surface roughness of cricket balls and then uses it to discriminate between new and old balls. Area-scale fractal analysis is used to find the surface roughness in order discriminate between the balls. FTEST (a statistical tool) is also used to establish a discriminatory criterion between the old and new balls. Wind tunnel test results are presented to show the relationship between the surface roughness and drag. Finally a correlation between the roughness and drag of the cricket is shown.
