为什么高尔夫球有酒窝? A Detailed Explanation
Dimples help reduce drag
The number and design of dimples on a golf ball affect its speed in flight, spin, and loft. Dimples that are deeper or shallower contribute to the amount of spin a ball makes during flight. While a ball with fewer dimples has more spin, a golf ball with deep dimples spins less. The size of the dimples is also important when determining spin.
Golf balls with dimples reduce drag by creating turbulent boundary layers. This increases the kinetic energy of air on impact and reduces the size of the wake. Golf balls with dimples can travel twice as far as those with smooth surfaces. 而且, a dimpled ball can reduce pressure drag to an incredible extent. The size and shape of dimples on a golf ball are just a few of the factors that make them so beneficial.
Golf balls with dimples can also accelerate faster than golf balls with smooth surfaces. This is because dimples create a region of low pressure above and high pressure below the ball. 在这段时间, the ball can gain more lift. 此外, golf balls with dimples are also less likely to produce backspin. Dimples reduce drag and enhance speed. 所以, golfers are advised to choose a ball with dimples to achieve optimal ball flight.
Dimples increase lift
The number of dimples on a golf ball determines the forces that affect the flight path and distance of the ball. A change in the depth of a dimple can make a huge difference in the trajectory and distance traveled. 而且, 50% of the lift is created by the backward spinning motion of the ball. This happens because the air pressure below the spinning golf ball is higher than that on top, causing the tennis ball to rise.
The dimples on a golf ball increase the lift of a ball by up to 25%. This is because a ball with dimples has a larger area of lift than a smooth one. This enables it to travel 25% farther and requires less force to reach the green. These characteristics have been measured experimentally by researchers in wind tunnels, but these experiments are not very reliable. There are several limitations to these tests, 然而.
The number and size of golf balls with dimples vary depending on the distance of the ball from the ground. 一般来说, the smaller the number of dimples, the lower the ball’s trajectory will be. 一般来说, 然而, every day golfers don’t need large dimples. Changing the frequency and size of golf ball dimples can also affect the ball’s trajectory and spin. The ball’s aerodynamic properties can be improved by making it dimpled, but not every dimple is necessary for a high-performance golfer.
They facilitate the ball’s motion in the air
The dimples on a golf ball are an important part of the ball’s aerodynamic design. The dimples promote an early transition into the turbulent boundary layer which reduces the size of the separated wake. The dimples on a golf ball can be as small as fifteen-hundredths of a millimeter. While the USGA does not regulate the size of the dimples, many golfers believe that they help improve the flight of the ball.
The dimples on a golf ball are shaped to allow a frontal airflow to pass through the over-pressure and depression regions. These dimples communicate with the depressions on the rear side of the ball, which facilitates aerodynamic air circulation. These features are a key part of golf balls because they allow the ball to rotate without losing momentum. This is one of the main reasons why the golf ball is so important.
