A Users Manual for SAMS (Small Arms Muzzle Simulator).

Abstract

A computer program 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. The computer program described in the users manual is called SAMS (Small Arms Muzzle Simulator). The finite difference technique used is summarized and a complete description of the program operation is presented. A sample case including input, and sample output is included. (Author)
