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 andor 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.
