Beginning Summary: First, I will test golf balls with dimples against golf balls without dimples. Which one goes farther / is more aerodynamic? Then I will use a simulation to find what happens with air currents in dimples and why dimples on golf balls reduce air drag / air friction. Design and create/build air current tubes to test the different effects of different size dimples. A big plastic tube with holes in the sides connected to a vacuum tube which then is connected to a leaf blower. The lower the projectile goes the more aerodynamically efficient it is because that means that the force of air friction is affecting it less. Utilize 3d printer to make golf balls with varying dimple dimensions than use the leaf blower to test each group to see how each variable effects how far it goes down the tube.
Final Summary: After finishing my project and testing both variables of dimple radius and dimple height in their effect on golf ball aerodynamic efficiency, I have come up with conclusive evidence. As the dimple radius on a golf ball increases, so does the aerodynamic efficiency of that golf ball. As the dimple depth or height on a golf ball is increased the aerodynamic efficiency will increase to a point but will eventually come to a peak and then start to decrease. From my testing, I have determined this point to be 0.03 inches, for a normal sized golf ball. At a dimple depth 0.03 inches the aerodynamic efficiency comes to a peak and after that point increasing the depth will make the golf ball less aerodynamic.
