The dimpled golf ball has a turbulent boundary layer instead of a laminar boundary layer. Uid dynamics (cfd) simulation of a golf ball has allowed deeper insight into the e ects of dimples. Most studies were conducted using the wind tunnel testing and computational fluid dynamics (cfd) simulation. In this paper experimentally studied the flow of fluid over a golf ball with dimples how the surface roughness impacts the drag on a sphere.
