Gun barrel wear studies based on physical kinetics

Abstract

In this article a study of the gun barrel wear mechanisms has been carried out. We construct a mathematical model based on the theory of ordinary differential equations. The model includes heat transfer and particle transfer into the gun barrel. The external parameters in the model are fitted to results from physical kinetics. Solving the differential equations give results for the temperature of the gun barrel along the gun barrel. We find agreement with experimental results. The heat flux into the gun barrel due to convective flow is very dependent on the flow pattern inside the cartridge of the projectile.
