Abstract

The experimental program presented in this paper explores a passive acoustic baseball bat swing speed measurement technique to aid in product development and certification and to gauge player performance. The collection of experimental information is performed in two facilities?a swing/hit facility and a wind tunnel facility. The data acquired are pressures and velocities in the vicinity of the bat. Potential flow theory is utilized to better understand the signals generated in the experimental collection of data and to determine the fundamental relations applicable to the subsequent flow field produced by a moving bat. The measured flow resembles potential flow but with a distortion due to bat acceleration. The theoretical and experimental results are compared, and a qualitative similarity in the results is established.
