Muzzle Flow in the Presence of an Anti-Recoil Plate: Exploratory Study

Abstract

Numerical analysis is attempted on the gasdynamics associated with flow over an anti-recoil plate. The blast field is analyzed under the assumptions that the presence of the precursor flow and projectile may be neglected. An existing shock-fitting code is used in order to determine its capability when computing impingement flowfields. While the code provided good prediction of the exhaust flow from the muzzle of the gun up until shock impingement, problems were encountered in treating the flow following this event. It is clearly demonstrated that a major reshaping of the code has to be undertaken in order to provide efficient computational grids.
