An Analytical Solution of the Heat Flow in a Gun Tube
Abstract
The analytical solution of the heat conduction equation for a gun tube (circular, thick-walled cylinder) assumed, for simplicity, to be of infinite length, is obtained. The temperature function is assumed to have axial and angular symmetry and, therefore, is dependent only upon time and radial distance. The axial flow has been neglected because the projectile moves through the tube at a much faster rate than heat can penetrate the tube. The initial and boundary conditions have been considered as close as possible to those encountered during the repeated firing of a gun. The temperature distribution in a barrel can be determined provided that the propellant gas temperature during the firing of each round is known and that the nature of the heat transfer from the gas to the barrel wall is known.
