Ball in Flight: The Aerodynamic Effects of Dimples on a Golf Ball

Authors/Creators

Description

This study presents a computational analysis of golf ball aerodynamics, comparing dimpled and smooth surfaces through physics-based flight simulation. The model integrates empirical wind-tunnel data to evaluate lift, drag, and spin-decay effects, providing quantitative insight into how surface texture influences trajectory and carry distance.
