Abstract

Considering the conductive properties of the propellant gas and the application potential of the plasma flow control, a magneto hydrodynamic model of the barrel is built and the magneto hydrodynamic control equations are solved by magnetic induction method. The effects of different magnetic fields on flow characteristics of the propellant gas in barrel are numerically studied. The results show that the ways of applied magnetic field and the magnetic field intensity are two main factors influencing the flow anisotropy. The effects of different ways of applied magnetic field on the velocity field of the propellant gas is different, and the corresponding application mode can be selected according to the actual demand. The Lorentz force induced in the plasma can reduce the friction force of the wall and the turbulence intensity of the gas that will result in the decrease of the friction coefficient and the heat transfer from the gas to the wall effectively. When the applied magnetic field is 1T and the conductivity is 5000s/m, the friction coefficient of the wall decreases about 8.7%
