The gas dynamics of a gun tube bore evacuator system or a gun gas operated chamber scavenger system may be theoretically described by ideal compressible flow relations. Differential equations and driving functions necessary to completely describe the operation of an evacuator system are developed based on the assumption of ideal adiabatic isentropic flow. A method of computer solution is proposed. Theoretical measures of scavenger effectiveness are presented.
