Book excerpt: A number of heat transfer studies have been performed in gun tube geometries especially those using folded ammunition. These analyses included the evaluation of the peak surface temperature using a new set of boundary conditions, time-dependent heat transfer coefficients and bulk fluid temperatures. The effects of uncertainties in the thermal properties and the effect of three surface coating materials were evaluated. A three-dimensional model of part of the folded ammunition geometry was developed and temperature histories for it were calculated over four rounds of firing. A thermal model was developed describing the temperature histories of a block sliding over a stationary surface. This model is an attempt at evaluating the thermal conditions in rotating band. The preliminary results are very encouraging. (Author).
