How Seam Inclination Influences Cricket Ball Swing

Abstract

Abstract. Cricket, a sport with origins in 16th century England, involves players attempting to manipulate the lateral motion of the ball to outwit the batsman. This is often achieved by adjusting the seam inclination or altering the ball's surface roughness. This paper specifically investigates how seam inclination affects cricket ball swing through computational fluid dynamics (CFD) simulations. The focus of the study is on conventional swing for both non-rotational and rotational cricket balls. The results indicate that seam inclination significantly influences swing, with an optimal angle between 58 to 60 degrees for the maximum lateral force of non-rotational cricket. This finding provides valuable insights into the mechanics of conventional swing and offers guidelines for bowlers to enhance their performance. The research explores the complex interplay between the ball's aerodynamics, seam inclination, and the resulting swing. By utilizing CFD simulations, the study delves into the underlying fluid dynamics that govern the ball's trajectory and the generation of lateral forces.
