Abstract :The bullet, which is activated by the firing of the gunpowder in the gun silencer, comes out of the gun\`s barrel. In the meantime, an irritating muzzle blast sound is heard that lasts for a few milliseconds. With this explosion, acoustic sound waves are formed that are independent of the bullet\`s path of motion. In this study, a silencer that can be attached to a low-power 9 mm firearm is modeled. Afterward, the impact of holes with the same area drilled in different geometries and angles on the diffusers insert ignore into journalissuearticles values(compartments); of the silencer are compared. The Computational Fluid Dynamics insert ignore into journalissuearticles values(CFD); analysis method is used for this comparison. In addition, the dynamic mesh model is used where the ballistic field changes over time. This mesh model is analyzed for imperforate, circular-holed, square-holed, and triangular-holed profiles with the same area. Depending on the analyses, the pressure, velocity, and dB results obtained for the silencer outlet area are compared with each other.
