A Model for Analysis of Secondary Combustion in Gun Exhaust Plumes

Abstract

An analytical model of the unsteady turbulent mixing and chemical reaction at the propellant-air interface in a muzzle blast flowfield has been developed. Particular attention has been given to the interplay between falling pressure and entrainment of variable-temperature gases as a key element of the processes leading to secondary combustion of the propellant in the gun exhaust plume. For the sake of computational economy, the model has been restricted to the axis of symmetry, and a two-layer integral-method has been developed. Instructions for use of the computer code are presented.
