Can the surface of a golf ball be made smooth
The surface of the golf ball was deliberately dented. The shape of golf balls is one of the achievements of aerodynamics. This is related to the turbulent transition and separated flow phenomena of the flow around the sphere. WheWhy don't golf balls have smooth surfaces  this is different from the flow around the spheren the flow around a smooth sphere, the turbulent transition occurs late, and the regular flow corresponding to the turbulence is called laminar flowWhy is golf not smooth
After the golf ball flies out, the direction is uncontrollable. However, the direction of modern aircraft and aircraft is controllableWhy is golf not smooth but uneven
The force behind the ball does not drop much, making the ball fly farther There is also a longer version of the explanation: the golf ball surface is designed with many small pits in order to make the golf ball fly farther. Statistics show that a golf ball with smooth surface is hit by a professional playerWhy golf balls are rough? Why not use smooth surfaces
The surface is smooth and the moving direction is fixed, which determines the force of air turbulence on the ball, that is, why the trajectory of table tennis has a horizontal arc. There are pits on the surface, which makes it difficult to form certain air turbulence. What can be formed is only a large number of turbulent flows with different directions and small forces, which interfere with each other and offset each otherGolf balls have low resistance due to rough surface, so why do airplanes require smooth surface
To put it simply, aircraft and golf are both different in terms of sports environment and volume! The potholes on the surface of the golf ball are mainly to prevent the air from creating a whirlpool behind the ball after passing through the ball, which will affect the flight of the ball. The aircraft itself is streamlined, which has solved this problem well, so it doesn't need to be considered! @Why should golf balls be made with a bumpy surface instead of a smooth one
Some 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 golf balls are designed to be concave rather than smoothWhy is the surface of a golf ball pitted rather than smooth? Why pitted balls
In order to increase the friction between the club face and the ball, and then produce overhang after hitting the ball! Increase the flight distance and control of the ball! You see, some players' balls fall back on the green and so onWhy is golf rough rather than smooth? What is the reason of fluid mechanics_ Hundred
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, resulting in higher pressure in the front. However, for the ball with dents, the air flow in the rear does not drop much, so that the ball can fly fartherWhy is the golf surface pockmarked
Initially, the surface of the golf ball was smooth. However, golfers have noticed that as the golf ball gets older, it will be full of scratches, potholes and cuts, which seems to make the ball fly farther. Golfers naturally use gravity to drive golf balls into the fairway, so golf balls are usually worn-out
