Simulation of Nonstationary Turbulent Flows in Devices For Reducing the Noise Level of High-Pressure Gas Media Moving with a High Velocity

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Features of the simulation of the thermodynamic and gasdynamic processes occurring in devices for reducing the noise level of a shot from a gun were considered. A simulation of large vortices in the nonstationary turbulent flow of powder gases in a muzzle noise reduction device with a silencer representing a shaped channel with several chambers, whose volumes decrease in the direction to the silencer outlet, has been performed. Results of qualitative and quantitative investigations of the initiation, development, and damping of the shock waves in the flow of powder gases, formed as a result of the firing of a shot made from a signal gun, are presented.
