Abstract
The present report aims to clarify the flow structures involving the stream-wise vertices which was generated on the dimple surface of golf ball. The experiments was carried out to obtain the velocity vectors around the flying golf ball. The boundary layer behavior was observed in detail and the separation was measured experimentally. Furthermore, the flow structure in the wake was investigated by examining the vorticities at the transvers cross section behind the golf ball. The results was compared with numerically obtained solution.
