9. The golf club head of claim 8 , wherein the first end of the front surface is positioned on the leading edge.
10. The golf club head of claim 1 , wherein: each adjacent pair of ridges is separate and spaced apart to define a space between the adjacent pair of ridges, and each ridge extends between the heel portion and the toe portion to define a width and extends between the face portion and the rear portion to define a length;
the length is substantially greater than the width for each ridge of the plurality of ridges;
the space between each adjacent pair of ridges is substantially greater than the width of each of the adjacent pair of ridges that define the space.
11. A golf club head comprising:
a crown, a sole, a toe end, a heel end, a face portion, a rear portion, and a leading edge between the face portion and the crown; and
a turbulator including a plurality of ridges disposed on the crown, wherein each ridge of the plurality of ridges includes:
a base positioned directly adjacent to the crown;
a top surface opposite the base of the ridge;
a ridge apex defined as a maximum height of the ridge measured in a direction perpendicular from the base of the ridge;
a front surface comprises a first end closest to the face portion and a second end closest to the ridge apex; and
a rear surface defining a portion of the ridge being closest to the rear portion of the golf club head, extending from behind the ridge apex towards the rear portion of the club head;
wherein:
the front surface defines a portion of the ridge being closest to the face portion, extending from near the face portion towards the rear portion of the club head;
the turbulator is positioned in a forward one-third portion of the crown in a front end to a rear end direction; and
at least one of the front surface, the top surface, or the rear surface includes two angled planar surfaces.
