If you are into golf, you are familiar with golf ball aerodynamics. But for those who are not, read on as this post will reveal to you informative insights about the aerodynamics of golf ball. To begin with, have you ever wondered when you hit the best shot and see the ball soaring? What makes it fly so far?
Your swing’s power plays a huge part, and the design of the ball as well. What appears as a plain ball us a marvel of engineering and science. Taking time to understand the movement of a golf ball in the air helps in designing better ones that can fly farther and higher.
Golf ball aerodynamics is sometimes not clearly understood mainly because the balls’ aerodynamic performance crucially depends on airflow details over the golf ball. Various factors regulate these details.
As the golf ball flies all through the air, this tends to develop a drag and lift forces. This depends on its spin rate, velocity, the conditions of the atmosphere. But most of all, the shapes of every dimple and its arrangement across the ball’s surface.
Predicting the ball’s performance is said to be harder than predicting a full-scale aircraft’s performance. However, there have been experimental works conducted to help individuals learn more about aerodynamics. Let get into the aerodynamics of golf balls.
Aerodynamics, which pertains to the science of how objects move through the air, has a lot to do when talking about golf ball aerodynamics. If you hit the golf ball, you provided initial momentum to such a ball. As this heads towards flight path and the hole, golf ball commonly pushes through the air, and this creates wind resistance.
Such resistance pushes back against the golf ball resulting in drag, which is known as the force triggering moving objects to move slowly. You’re allowed to drag the wind against your face when riding a bicycle downhill or determine its power if you attempt to hit the golf ball directly to the wind.
Nevertheless, golf balls often include backspin, and due to this, air moving on top of the ball moves quicker than air moving underneath the ball. The quicker the movement of the air, the fewer amounts of pressure that it exerts, and this effect are known as Bernoulli’s Principle. The low pressure air on top of the golf ball helps in generating lift, which is known as the force pushing the ball upward and helping it travel beyond. The drag and lift forces pose effects on how far and high the golf ball can actually move.
The golf balls’ aerodynamics is known to be more complex as compared to spherical balls. The roughness in the surface in dimples form plays a part in intensifying the complexity level and the air flow’s three dimensionalities around the ball. In some studies, it has also been revealed in prior studies that individuals sometimes misunderstood golf ball aerodynamics because of its varied dimple shape, pattern, depth, and size.
Present studies measured the drag coefficient experimentally of a wide range of golf balls that are available commercially under an array of wind speeds. It has also been found out that the ball’s drag coefficient significantly varies because of different dimple geometry.

I am probably one of the many that came to the extent of asking what’s with these dimples? Something different than most golf balls share practically in common is dimpling. These are known as the small dents throughout the golf ball. Dimples may appear to be there only for decorations; however, they really have a particular aerodynamic purpose.
Thinking back to the nineteenth century, players found that old dented gutties flew past the new ones, so they started hammering dents to them purposely. At that point, they might not have known precisely why these dents made a difference and how these could help. However, we already know this is because of the flaws that created the turbulence on the airflow around the moving golf ball, making its wake thinner and minimizes drag.
Dimples likewise add in spins. As the ball pushes ahead through the air, dimples trigger the ball to turn in reverse, pulling the airflow downwards. As this scenario occurs, the air at the base of the ball pushes against the ball (Newton’s Third Law), making more lift. Dimples are, therefore, minor design features with a major effect.
The dimples found in golf balls create a thin air layer turbulent boundary which clings to the surface of the ball. This allows smooth airflow following the surface of the ball a bit further around the ball’s backside, thereby reducing the wake’s size. Dimpled golf balls, therefore, include half the drag of the smooth golf ball.
Dimples likewise affect lift. The small ball that includes backspin tends to create lift through warping the flow of the air to the extent that the ball acts like an airplane’s wing. Its spinning action results to the air pressure on the golf’s ball bottom is higher as compared to the top most air pressure. Such imbalance can result in an upward force in the golf ball. The other half is offered by dimples that allow for the lift force’s optimization.
Wind tunnel technique was developed to measure the aerodynamic forces that act into the golf ball. Golf balls with round and hexagonal dimples were further studied and investigated. It has been found out that dimples induce crucial Reynolds number behavior at lower Reynolds number value as compared to that experienced by seamless and smooth sphere over at this point, unlike the sand-roughened sphere’s behavior. There’s a minor reliance on the further increased force in the Reynolds.
The hexagonally dimpled golf ball got more coefficient and a bit of a lower drag as compared to the round-dimpled conventional ball. The trajectories are commonly calculated with the use of aerodynamic data. The ranges are then being compared to the data taken from the driving machine in the golf course.
If you are inexperienced with golf, taking time to learn about golf ball aerodynamics can be of great help to become better at golf. The golf ball aerodynamics covers a wide range. However, learning about this could help you gain clearer insights about the connection of aerodynamics to the ball movements. Additionally, how it affects the golf ball’s flight, how the golf ball aerodynamics is measured, and many more. Your knowledge about this can help you improve the way you handle and manage your ball while playing golf. Thanks for reading.
