- 在流体计算软件fluent的微分方程中加入电磁项,可以计算电磁场作用下的流场。本文介绍了电弧推力器的理论模型,计算了电弧流场,并将计算结果和试验数据进行比较。分析了欧姆加热对提高工质气体比冲、降低推进剂消耗的作用,并根据流场温度分布,估计了电弧对电极的热烧蚀情况,提出了相应的解决方案。
- 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.
