How Do Golf Ball Dimples Affect Lift and Drag?
- As the air hits the dimples on a golf ball, small pockets of turbulence are created. ...
- The air flowing over the ball thus sticks closer to the ball’s surface and flows off the ball further back.
- This creates a smaller wake, which means less drag and a ball that flies farther and smoother.
Why do golf ball dimples reduce drag?
Golf ball dimples reduce drag by creating a turbulent boundary layer flow around the ball. The boundary layer is defined as a thin layer of fluid dragged by the ball. By creating this turbulent boundary layer, the separation point decreases.
How do dimples decrease drag?
First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.
Do golf ball dimples affect putting?
It makes no claim that its ball putts better. The scientific improvements in ball design give you the opportunity to find the perfect ball that gives you the ball flight you want to achieve. However, the different concave configurations on your golf ball will do nothing to improve your putting.
Is it better to have more or less dimples on a golf ball?
The number of golf ball dimples is less important than the shape and depth of the dimples. The number of dimples can affect drag, so it is important to not have too many dimples. Between 330 and 400 dimples is the optimum number. More dimples mean more focussed control over the ball trajectory.
How many dimples are on a Titleist Pro V1 golf ball?
388 dimpleNew Spherically-tiled Tetrahedral Dimple Designs– featuring a 388 dimple layout for Pro V1, and 348 for Pro V1x – are optimized to each model to maximize distance and flight consistency. Pro V1 maintains its penetrating trajectory while Pro V1x will fly higher than the prior generation.
Why are there 336 dimples on a golf ball?
Essentially, golfers would have little hope controlling a smooth golf ball. When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.
What is the purpose of putting dimples on the surface of materials?
The smooth sphere separates the air rapidly, creating a large pressure differential between the front and rear of the ball. This creates a large wake that creates lots of drag, forcing the ball to descend more quickly. In contrast, the dimpled ball delays the separation of the air, reducing the size of the wake.
Why is a golf hole 4.25 inches?
Four-and-a-quarter inches in diameter. R&A ADOPTS 4.25-INCH HOLE SIZE That first hole-cutting implement utilized a cutting tool that was, you guessed it, 4.25 inches in diameter. The folks running the R&A apparently liked that size and so adopted it in their rules for 1891.
How many dimples are on a professional golf ball?
Generally, the number is anywhere between 300 and 500 dimples. American golf balls, more often than not, come with 336 dimples. While how many dimples on a British golf ball, they have 330 dimples. As for the highest number of dimples, that would be Ultra 500 Series Golf Balls (500 dimples).
How many dimples does a Callaway SuperSoft golf ball have?

How many dimples are on a Callaway chrome soft golf ball?
332 dimplesHowever, throw it over to another popular golf ball such as the Callaway Chrome Soft, and you get 332 dimples.
Dimpled golf balls have less drag than smooth golf balls
Ever wonder why golf balls have dimples? It’s because the texture of the surface of a golf ball creates more turbulence on one side than the other. This causes air to flow around it more quickly on one side, reducing drag and improving distance.
The dimples on a golf ball create turbulence in the air that reduces the pressure on the ball as it moves through the air
Golf balls are created with either dimpled or smooth surfaces. The dimples on a golf ball create turbulence in the air that reduces the pressure drag on the golf ball, thus increasing distance.
The turbulent flow of air over a golf ball also creates lift, which is why you can hit a duffed shot and still get some distance from it
The turbulent flow of air over a golf ball also creates lift, which is why you can putt with a dimpled ball and it doesn’t roll as far. A smooth golf ball has drag due to the laminar flow of air over its surface.
Dimpled golf balls are more aerodynamic
Dimpled golf balls are more aerodynamic because they create an uneven surface for the air to flow over. This is due to their dimples, which act as tiny bumps on the surface of a smooth ball that provide turbulence in the airflow.
As a result of their design, dimpled golf balls travel faster off your club face and go farther with each swing
Did you know that dimpled golf balls have less drag than smooth golf balls? What does this mean for your game? Well, a study by the University of Western Australia found that a ball with more surface area on the club face will travel faster and farther off the tee.
Dimpled golf balls are more likely to travel further due to the reduced air resistance
Dimpled golf balls are more likely to travel further due to the reduced air resistance. A dimpled ball is less smooth and, therefore, has a lower drag coefficient than a similarly sized smooth ball. Dimples create pockets of low pressure in front and behind the ball which reduces the flow of air over its surface.
Dimples also help create turbulence in the boundary layer next to the surface of a ball
Ever wondered why dimpled golf balls have less drag than smooth golf balls? It’s because of the turbulence created by the dimples in the boundary layer next to the surface of a ball. The flow pattern over a smooth sphere is laminar, but it becomes turbulent when there are surface irregularities like those caused by dimples.
Which shape is the most effective for golf balls?
Also of interest is the fact that to date all dimples experimented with in racecar terms have been circular or oval in shape, yet Golf research has suggested that hexagons are actually the most effective shape (on balls at least).
Does Zipp have a dimpled hub?
Whilst not exactly dimple s in the Zipp sense the ‘turbulator’ wing used by Oak Racing in LMP1 exploits a similar concept. As well as its work with wheels, Zipp has also developed a dimpled hub for racing cycles, which suggests areas such as the driveshafts on a single-seater racecar could perhaps benefit similarly.
How Do Golf Ball Dimples Work?
Any object moving through the air faces the force which the air exerts on it. There are two components to the force an object flying through the air undergoes:
How Do Golf Ball Dimples Improve the Game?
Now that you understand at least a bit of the aerodynamics involved with golf ball dimples, you can look at how exactly this appears in an average round of golf. For the player, golf ball dimples serve two purposes:
Have Golf Balls Always Had Dimples?
Golf has been around for a long time, and for a lot of that time, people played with smooth balls. However, at some point in the 1800s, players noticed that their dented golf balls actually performed better than the perfectly smooth ones.
Are All Golf Ball Dimples the Same?
After learning how vital dimples are to a golf ball’s success, you may be surprised to learn that golf ball dimples are not regulated. They can have different shapes, different depths and appear in varying amounts on balls.
Golf Ball Dimples Are Not Everything
There are other things that go into how smoothly and how far a golf ball flies beside the dimples.
Conclusion
Two key forces affect your golf ball’s flight: drag and lift. Golf ball dimples have a massive impact on both, which is why they are so crucial for effective golf balls. Dimples reduce drag and increase lift.
Take Action – What You Can Do Today to Get Better
What does this mean for you? I believe in the following recipe to get better:
How does the number of dimples affect the drag of the golf ball?
This means that if you prefer a golf ball to move a little more slowly through the air to compensate for a specific swing or hit style , then the highest number of dimples you can find will be the way to go.
Why do golf balls have dimples?
Dimples do make a golf ball fly farther. Without dimples, golf balls do not spin well and have too much drag while in flight to travel a long distance.
Why do dimples affect the distance the ball can go?
The reason why dimples affect the distance the ball can go is because the dimples on the surface of the ball cause the ball to spin in the air. This backspin motion creates a low-pressure zone behind and underneath the ball while in flight, effectively pushing the ball upwards, which translates to longer air-time.
How many dimples does a 1070 have?
The Dimple 1070 has 414 large dimples and 656 small dimples, making it a non-regulation golf ball. The Mizuno RB 566 is a regulation ball that has 566 micro-dimples, which are more dimples than any other regulation golf ball.
What affects the spin of a golf ball?
The spin of the ball is affected by the depth of the dimples. Shallower dimples mean more spin. The way the dimples on a golf ball are shaped and laid out is more important than the actual number of dimples on the ball.
Why are dimples important in golf?
The dimples on a golf ball are crucial. They determine all of the major aerodynamic properties of a golf ball, which ultimately determines how well the ball performs during a game. More dimples on a golf ball do not necessarily make the ball better, but rather the way the balls are laid out and how they are designed.
Why is a lower number of dimples better?
Having a lower number of dimples will result in less drag, and so the ball with move more quickly through the air, being slowed down less by the air around it. If you prefer a fastball, then choosing one with a lower number of dimples is a better option for you.
