Abstract We numerically study the effect of background pressure on supersonically flowing plasma through open field lines. Ions and neutrals are treated by particle-based Direct Simulation Monte Carlo (DSMC) method, while electrons are treated as a fluid in order to save memory and calculation time. We find that the ion temperature and velocity profile are different from those of neutral particles. The number density and temperature of residual gas affect on ion’s temperature and velocity profiles.
