In order to solve the problem of serious ablation of weapon tubes, a method is presented to reduce ablation of high temperature gas on the barrel bore surface by application of magnetron plasma. The turbulent dissipation model of high temperature conducting gas in a cylinder structure is constructed by using the magnetic fluid description method. Numerical simulation of the flow and heat transfer characteristics of conductive gas in a cylinder are studied, along with the effects of different magnetic field directions on the wall temperature of the cavity. The effect of a vertical magnetic field on the heat transfer characteristics of the conductive gas is tested by infrared thermal imaging technology. The results show a that magnetic field can effectively reduce the turbulent kinetic energy of conductive gas, and its distribution has the characteristics of anisotropy. Turbulent kinetic energy along the magnetic field direction is significantly lower than that in the direction perpendicular to the magnetic field. The magnetic field perpendicular to the flow direction of the conductive gas can weaken its heat transfer capacity.
