Unsteady Heat Transfer Analysis for any Ammunition, Gun, and Firing Schedule

Abstract

The propellant gas convective heat transfer problem is divided into several subproblems: Generation of thermochemical properties for any chosen propellant; analysis of transient, inviscid, compressible flow through the gun barrel; analysis of unsteady, viscous, compressible flow with arbitrary pressure gradients on the bore surface; analysis of transient heat diffusion through single or multi-layer gun tubes; analysis of unsteady free convection and radiation around the gun tube; and control of a sequence of procedures due to the nature of unknown and transient boundary conditions and also due to coupling between the problems.
