Aerodynamics of Golf Balls

Introduction to aerodynamics Aerodynamics is a study of the movement of objects moving against gaseous fluids and fluid / air. In other words, aerodynamic studies are fluid dynamics studies that are particularly relevant to the gas state of air and matter. When an object passes through a fluid / air, two types of flow characteristics, laminar flow and turbulence occur. Laminar flow is a smooth and stable flow on a smooth surface with almost no interference. Intuition will lead to the belief that this type of airflow is desirable.

Flying UK scientist P.G. Tait conducted the first aerodynamic experiment using a golf ball in 1887. 2 Professor Tait showed the importance of rotation for golf flight through his research. When he was young he said he was taught that "all turns are harmful" he said 2 He vigorously practiced hitting the ball with almost no rotation. After finishing his research, Tate wrote that "At least 35 years is too late now, I understand." Professor Tait explicitly stated that the ball, which is driven to rotate around the horizontal axis with the top of the ball facing the golfer, has a lifting force to hold the air longer than when the ball is not empty. Scientists observe the competing effects of lift and resistance. Although it is possible to generate equations and solutions for various swings and speeds and propose the best lift drag ratio, it is already statistical.

The aerodynamics of working on a golf ball is why the flight of the ball is so unique that any golfer who can hit a straight line prove. If the person watching the flight of the golf ball is standing behind the golfer, he will not see a parabolic arch as expected. Instead, the ball rises linearly for a few seconds and then slowly falls to the earth. According to the first law of Newton (unless a force acts, the object continues to move at a constant speed along a straight line), it seems impossible for the path of the observed ball to be impossible. The designer of the golf ball instantly points out that it is aerodynamics that moves vertically at a collapse, rotation, ball, and high speed balancing with gravity, so that the motion on the path becomes nonuniform .
