FastSkinz Dimpled Skin Offers Better Aerodynamics
February 17, 2009 by admin · Leave a Comment
Uneven surfaces cut wind resistance, allowing objects to move through the air faster. This is converse to the accepted notion that a smooth surface will be faster, which is true up to a point, usually the point where the air is leaving the surface of the travelling object. This is why golf balls are dimpled. Such flow separation causes a large increase in the pressure drag, but it is advantageous to deliberately trip the boundary layer into turbulence at a point prior to the location of laminar separation. Although the skin friction is increased, overall drag is decreased. Read more
