Abstract

A vortex generating golf ball dimple for producing a turbulent boundary layer on the surface of a golf ball during its flight is a composite of a plurality of overlapping smaller concave sections. Preferably, the dimple is a plurality of peripheral spherical sections overlapping a central spherical section to form a ridge-like polygon. The polygon, the top edge of which lies below the outer edges of the dimple, acts as a vortex generating structure within the dimple concavity for producing the turbulent boundary layer. Each pair of opposite or near opposite sides of the polygon has a common cross-sectional shape or structure. The aerodynamic characteristics of the cross-sectional structure are such that the turbulent boundary layer is formed about the dimple at even relatively low velocities without any unnecessary interference being produced at high velocities. Because the cross-sectional structure is seen across the dimple from a plurality of orientations, the boundary layer producing effects of the dimple are directionally independent.
