Abstract: | The high pressure waves generated due to muzzle blast flow of tank gun during firing is a critical issue to examine. The impulsive
noise from the gun has various negative effects such as damage of human bodies, damage of structures, creating an environmental,
social problem and also military problems such as exposure of location of troops. This high pressure impulsive sound, generated
during the blast flow, was studied and attenuated. An axisymmetric computational domain was constructed by employing Spalart
Allmaras turbulence model. Approximately 90% of pressure and 20 dB of sound level are reduced due to the use of the three
baffle silencer at the muzzle end of the gun barrel, in comparison with the tank gun without silencer. Also, the sound pressure
level at different points in the ambient region shows the same attenuation in results. This study will be helpful to understand
the blast wave characteristics and also to get a good idea to design silencer for large caliber weapon system. |
