    Abstract
  • The characteristics of flow and heat transfer for plasma controlled by external magnetic fields in the convergent nozzle and the jet wrapped by the plasma were simulated using the models of magnetic induction equation,the multiphase flow mixture and modified turbulent two-equations under magnetic forces.The results show that the plasma volume fraction decreases with the acceleration of flow in the convergent nozzle.Magnetic intensity increase may improve the plasma volume fraction near the wall and suppress its turbulence strength,thereby cutting down the increase of nozzle wall temperature effectively.The rising wall temperature is reduced by 54.4%,the thrust coefficient is increased by 0.74% and the jet is still wrapped at 4D* from the nozzle exit after applying the 1.3 Tmagnetic field.
