Abstract

golf ball is a very interesting aerodynamic device. As a sphere, the coefficient of drag should be about 0.48. However, because of the surface of the golf ball, the drag coefficient can be much lower, up to 12%. This paper explores the multitude of ways, designs and concepts that create such a lower drag coefficient, through computational fluid dynamics analysis, and using those findings how to use them when designing new parts to increase the efficiency and reliability of the device that uses said parts while increasing the quality of life of the user of the devices.
