th 17 Australasian Fluid Mechanics Conference Auckland, New Zealand 5-9 December 2010 A Comparative Study of Golf Ball Aerodynamics F. Alam, H. Chowdhury, H. Moria, R. L. Brooy and A. Subic School of Aerospace, Mechanical and Manufacturing Engineering RMIT University, Melbourne, Victoria 3083, Australia Abstract The aerodynamic behaviour of the golf ball is primarily Choi et al. [7], Smith et al. [10] and Ting et al. [ 11] on golf ball dependent on the physical features of complex dimples. The aerodynamics under spinning and non spinning conditions and dimples vary in sizes, shapes and depths which generate complex their findings were published widely. However, the effects of aerodynamic flow pattern around the ball. Although some studies dimple characteristics on golf ball aerodynamics remain a have been conducted on golf ball aerodynamics, the aerodynamic mystery. Some studies conducted by the commercial golf ball behaviour of dimple characteristics is not fully understood. The manufacturers are kept in-house due to the stiff market primary objective of this research is to experimentally evaluate competition. A very little information is available on the latest the aerodynamic properties (drag, lift/down force) of a series of development of golf ball in the public domain. Therefore, the commercially available golf balls. Each of these new balls has primary objectiv
