A Digital Computer Program to Determine the Two-Dimensional Temperature Profile in Gun Tubes

Abstract

The study was undertaken by the Research Directorate, Weapons Laboratory at Rock Island, to develop a digital computer program by which the two-dimensional temperature profile in gun tubes can be computed under realistic physical conditions. A mathematical model was presented in which variable geometry, temperature-dependent thermal properties, and variable conditions at the boundaries are considered. A numerical algorithm, in which the method of explicit finite-differences is used, was developed for the mathematical model and was programmed for the digital computer. A numerical example was computed to check the computer program. The program and all sub routines functioned properly. No numerical instability nor convergence problems were encounterd.
