A Numerical Method for the Simulation of Muzzle Gas Flows with Fixed and Moving Boundaries

Abstract

A numerical technique for the simulation of the time dependent, axisymmetric flow of muzzle gases exiting a gun barrel with the attendant flow of ambient air is described. The technique is based on modifications to the OIL Eulerian hydrodynamics computer program to include treatment of arbitrary fixed and moving solid boundaries. This capability permits the inclusion of complex muzzle device geometry and a moving projectile in the Eulerian finite difference mesh.
