WebAnswer (1 of 5): Believe it or not, you’re looking at it backwards. Dimples create drag. The key point in the explanation is that every golf ball that is flying through the air has both a forward, linear velocity, and a reverse rotational motion, or … http://www.fluid.tuwien.ac.at/302042?action=AttachFile&do=get&target=golf_ball_dimples.pdf
WebThe plume is initially laminar, but transition to turbulence occurs in the upper third of the image. The image was made by Gary Settles using a one-meter-diameter schlieren mirror. ... Lift and drag properties of golf balls … WebA smooth ball with otherwise identical physical properties, launched in the same manner, will only travel about 140 yards. The reason for this is that when the golf ball passes through the air, the roughened surface …
WebDec 8, 2012 · Golf balls are dimpled to give the ball some grip on the air. Backspin is usually highly desirable as it increases lift and hence further distance. ...

On the wing of this aircraft, you can see vortex generators fitted along it's length. From Wikipedia Turbulent Flow …
WebAug 4, 2011 · Because the drag on a golf ball is dictated by the separation points, you will need some method to determine where those occur. That will require a boundary layer solver. Of course, the whole point of the …
WebThe boundary layer generates wake turbulence after a short interval. In baseball, this effect is used to generate the downward motion of a curveball, in which the baseball is rotating forward (with 'topspin'). ... : § 4.5 Backspin (upper surface rotating backwards from the direction of movement) on a golf ball causes a vertical force that ... limoncello lemon sorbet with or without mintWebShop for Used Cobra RADSpeed Gloss Turbulence Gray/Turbo Yellow Driver in Very Good Condition at 3balls.com.
