Heat Transfer Simulation of Large Caliber Gun Barrel

Abstract

Abstract During the continuous firing of artillery, the inner wall of the barrel will experience a continuous rise of temperature, which has much to do with the ambient temperature and the way it cools. For artillery using combustible cartridge, the temperature rise of the barrel’s interior wall will have a great impact on the safety of combustible cartridge during successive shots. The finite element model of gun barrel was established by ANSYS software while the convection heat transfer in the inner and outer walls of the barrel and the heat transfer in the barrel wall were simulated. This paper observed the temperature variation of the inner and outer wall of the barrel under different ambient temperatures and different cooling methods, revealing that the higher the ambient temperature, the faster the barrel temperature rises. Different cooling methods have little influence on the inner wall temperature, which would emerge long after shooting. The research provided theoretical basis for the safe use of combustible cartridge cases.
