FORTRAN Program VENT; An Analysis of Muzzle Gas Venting,

Abstract

Program VENT is a set of FORTRAN instructions for solution of the set of partial differential equations governing the one-dimensional unsteady flow in a duct of variable area. The intended application of the program is analysis of the venting of propellant gas from the muzzle of a gun; the variable area includes axial variations in the bore and/or vent diameter and time variations due to passage of the projectile. The computational domain consists of two regions: the first extends from a leading expansion wave to a contact surface and contains only propellant gases; the second extends from the contact surface to a leading shock and contains only shock-heated air.
