Study of Heat Transfer and Erosion in Gun Barrels

Abstract

This study models the combustion, solid propellant movement, gas dynamics, projectile dynamics, transient boundary layer, heat transfer, and barrel metal temperatures in a gun barrel. This is accomplished by rigorous development of the coupled partial differential equations and carrying out a detailed numerical solution to these equations. Comparison of barrel temperature solutions to experimental data is shown. Erosion mechanisms are discussed in the light of these solutions. This model is then used to study hypotheses concerning the heat transfer, temperature, and erosion effects of submicron size solid particle additives (TiO2) to gun propellants. A mechanism not previously studied offers excellent theoretical results in explaining the reduced erosion.
