| Abstract: | Flow with electromagnetic field can be calculated by Fluent simulation software improved with electromagnetic item. The theoretic model is presented. Research of thermal flow field of arcjet is done through the numerical simulation method. The simulation results are compared with experiment data. The heating effect of plasma torch for improving impulse and saving propellant is evaluated. The ablation of electrode is estimated based on calculation results of temperature. |
