Finite Difference Calculations of the Free-Air Gun Blast About the Muzzle of a 5in./54 Naval Gun

Abstract

A two-dimensional hydrodynamic code has been used to calculate the free-air blast field about the muzzle of a 5-in./54 cal Naval gun. The calculated blast pressure wave as a function of time is presented along with the velocity field. Calculated overpressures and durations are compared with experimental data. The calculations predict the formation and location of the shock bottle and formation of the 'smoke ring'.
