Why is the surface of a golf ball full of pits? What are the benefits of this design
Compared with the smooth ball, when the ball with pits moves in the air, it certainly increases the friction resistance, but it greatly reduces the differential pressure resistance. Considering comprehensively, the resistance of the ball with pits is much smaller, which is more conducive to the flight of the ball. When a golf ball moves at a high speed in the air, in addition to the frictional resistance of the airWhy does a golf ball with a dent fly farther than a smooth ball
The surface of the ball is not smooth but dented. The reason is that in aerodynamics, the ball is placed in the air flow and surrounded by a thin interface layer. If the surface is smooth, the interface layer is easy to peel off, resulting in air flow vortices in the rear, causing higher pressure in the front, while the air flow behind the dented ball does not drop much, so that the ball flies fartherWhy is the surface of a golf ball uneven rather than smooth
The other half comes from small pits, which can provide the best lift. Most golf balls have 300 ~ 500 small pits, and the average depth of each pit is about 0.025 cm. Drag and lift are sensitive to the depth of the pit: even if there is only a small difference of 0.0025 cmWhy is golf not smooth but uneven

Many dents have been deliberately made on the surface of golf balls. The shape of golf balls is one of the achievements of aerodynamic research. This is related to the turbulent transition and separated flow phenomena of the flow around the sphere (that is, the flow around the sphere). When flowing around a smooth sphere, the turbulent transition occurs late, and the regular flow corresponding to turbulence is called laminar flow. AndWhy is golf uneven
The uneven surface of golf balls is actually to make golf balls fly farther and have less resistance. In fact, when golf was first designed, it was not uneven, but in the process of slow development, people found that it seemed that the uneven shape was more conducive to the flight of the ballWhy should golf balls be made with uneven surfaces instead of smooth ones
Studies have found that after a smooth golf ball is hit with all its strength, compared with a golf ball with a concave surface, the flying distance is only half of that of a golf ball with a concave surface. This is why people design golf balls with concaveComparison between smooth golf ball and concave golf ball  of course, it increases the friction resistance surfaces instead of smooth onesThere are many pits on golf balls. What are the functions of these pits
Compared with the smooth ball, when the ball with pits moves in the air, it certainly increases the friction resistance, but it greatly reduces the differential pressure resistance. Originally, golf, like table tennis, has a smooth surface. It's just that people inadvertently find some old and rough balls when playing golfSmooth Golf Yu concave hole golf in the air movement of the same difference! (detailed)
It turns out that the scratched ball has better flight ability than the smooth new ball. Therefore, according to the principle of aerodynamics, scientists designed golf balls with concave surfaces. These pits make the stability and distance of golf balls more advantageous than smooth balls
