For many years, perhaps even from the inception of the game itself, cricket players and spectators have been drawn to the aerodynamic properties of a cricket ball. We have compared the lift force and drag with observations. The Detached Eddy Simulation model (DES) has been used to provide a 2D numerical simulation of a cricket ball. DES was effectively used to simulate the cricket ball's lift and drag forces at various ball speeds, seam angles, and roughness heights. This study focuses on the computational fluid dynamic simulation of the cricket ball in the flow field. The flow field at different roughness angles 45° to 90° with a gradient of 15°, roughness heights in a range of 0.1 to 1 mm, and three bowling velocities of 32.77,35.55, and 45.55 m/s have been computationally analyzed. Aerodynamic forces were obtained using numerical analysis, while boundary layer separation sites were obtained through analysis. The aerodynamics of a cricket ball were proven by comparing the boundary layer separation width and asymmetry to the drag and lift forces.

摘要

For many years, perhaps even from the inception of the game itself, cricket players and spectators have been drawn to the aerodynamic properties of a cricket ball. We have compared the lift force and drag with observations. The Detached Eddy Simulation model (DES) has been used to provide a 2D numerical simulation of a cricket ball. DES was effectively used to simulate the cricket ball's lift and drag forces at various ball speeds, seam angles, and roughness heights. This study focuses on the computational fluid dynamic simulation of the cricket ball in the flow field. The flow field at different roughness angles 45° to 90° with a gradient of 15°, roughness heights in a range of 0.1 to 1 mm, and three bowling velocities of 32.77,35.55, and 45.55 m/s have been computationally analyzed. Aerodynamic forces were obtained using numerical analysis, while boundary layer separation sites were obtained through analysis. The aerodynamics of a cricket ball were proven by comparing the boundary layer separation width and asymmetry to the drag and lift forces.
