Golf surface intentionally making many dent
Golf surface intentionally making many dent. Golf is
the shape of the air to study the dynamics of one of the results. This and sphere (that is, the flow around the sphere of unprecedented turbulence flow) turn and separated flow phenomena. Smooth spheres, turbulent current around the turn of the late, and unprecedented happened turbulence corresponding rules laminar flow called. And the laminar boundary layer is easy to occur flow points golf phenomenon (i.e., streamline from off the ball surface), cause behind the larger ball dead zones, generates a lot of resistance (form resistance). Make golf flight distance is very small. And sphere surface is dent, dent turbulence happen to turn the aerofoil fengwen.on turbulent boundary layer, it's not easy to change flow separation phenomenon, so that the ball behind the small dead zones, reduce the resistance. Make golf flight distance increased. The turbulence of the friction laminar than, but compared with form resistance, got up a small role, and the resistance or smaller. Golf surface of small, yea, also can have prompted separation function, but the bumps of the flow interference some difficult to control, causing some lateral force (also can call lift).
