Calculations of Internal Ballistic Flow with a Projectile to Wall Gap

Abstract

The flow near the conjunction of the base of a moving projectile and the gun tube wall, with and without a 1% gap, has been simulated using the SAGITA code. Results are presented for both a 20 and a 40 mm gun and the predicted flow configurations were checked by several mesh refinement studies.
