Dynamics and Acoustics of Water Entry
Abstract
ABSTRACT:Despite considerable basic research into solid bodies entering the water, the advancement of naval technologies such as air-dropped weapons is still hampered by a lack of fundamental understanding in several key areas. Significant knowledge gaps still exist concerning: (1) the acoustics associated with water entry, (2) impact forces and means of mitigating them and (3) the water entry behavior of bodies in a wave field. Furthermore, it is unclear if past laboratory scale studies of water entry phenomena translate to larger scales and higher speeds. The proposed research aims to fill in the three identified knowledge gaps through basic experimental studies and complementary physical modeling of sphere and slender body water entry. Additionally, canonical features of water entry {such as the type of cavity formation} will be examined through experimentation at larger scales and speeds than have been previously studied.
