Cooling Methods for Gun Barrel

Abstract

This paper investigated the effect of mid-wall water cooling for the gun barrel under continuous firing. A 2D cross-section model of the gun barrel is adopted and the cooling channel is circular. An interior ballistics code is used to determine the inner wall convection boundary condition, providing gas temperature and heat transfer coefficient. Results of temperature histories of the inner wall and outer wall and temperature distributions are presented. The results show that this cooling method can slow down growth rate of the peak temperature of the inner wall.
