Patent ID: 8353789

Claim:
A golf ball having recessed dimples on the surface thereof, wherein at least one dimple is defined by a protrusion formed on an inner surface, the protrusion comprising a plurality of rotational elements whereby a boundary layer of air flowing over the surface of the dimples is energized, wherein an acceptable number of rotational elements for each dimple is determined by the number of dimples on the golf ball, such that: N E ≤ 4000 N D and, wherein a final dimple layout is defined by: V D =V O −( N E V E ) wherein: N E is the acceptable number of rotational elements for each dimple; N D is the number of dimples on the golf ball; V D is the chordal dimple volume; V O is the phantom chord volume; and V E is the elemental volume of the protrusion.
