Abstract

In this study a heat transfer phenomena in a gun tube using Differential Quadrature Method was examined. The phenomena was dealt in a two dimensional transient manner. In order to apply a general condition to the problem, the internal volume of the cylinder was divided into two distinct zones. One zone was exposed to a fluid with high temperature and high pressure conditions due to the burning of the propellant. The other zone was exposed to a fluid in environmental condition. As the time passes, the bullet moves toward the front zone. Therefore the volume of the rear zone increases, while the volume of the front zone decreases. The boundary conditions of the internal boundary nodes are determined due to the axial position of the bullet. The boundary condition of the nodes located in the rear zone are set to the high temperature and high pressure fluid, while the boundary condition of the front nodes is set to standstill fluid conditions. According to the mentioned conditions, general transient heat conduction equation in cylindrical coordinate was utilized and temperature distribution of the gun tube was extracted for numerous rounds. Finally an experimental study was examined to validate the proposed method. A comparison between the simulation results and experimental results shows a high consistency between them. The results of this study can be used for stress analysis of gun tube and estimation of its erosion and lifetime.
