A numerical design method to determine basic specifications of high‐performance frozen inert gas plasma (FIP) MHD generators is proposed. To validate the proposed method, time‐dependent, two‐dimensional (r‐z)MHD numerical analyses are performed for several FIP MHD generators with different thermal inputs (30, 100, 300, or 1000 MW) designed by the proposed method. The numerical results indicate that the designed FIP MHD generators with the thermal input of 100 MW or more are able to be operated with the performance approximately same as the designed one. For the designed MHD generator with the thermal input of 30 MW; however, the performance shown by the MHD numerical analysis is considerably lower than the designed one. For such a case, the performance can be improved by operating the MHD generator under an applied magnetic flux density larger and an inlet ionization degree lower than those designed values.

冷冻惰性气体等离子体MHD发生器的数值设计方法研究

提出了一种确定高性能冷冻惰性气体等离子体（FIP）MHD发生器基本规格的数值设计方法。为了验证所提出的方法，时间相关的二维（r - z通过提议的方法设计了几种具有不同热输入（30、100、300或1000 MW）的FIP MHD发电机的MHD数值分析。数值结果表明，所设计的热输入功率为100 MW或更高的FIP MHD发电机能够以与所设计的发电机大致相同的性能运行。对于设计的MHD发电机，其热输入为30 MW；但是，MHD数值分析显示的性能大大低于设计的性能。对于这种情况，可以通过在施加的磁通密度更大且入口电离度低于那些设计值的条件下操作MHD发生器来提高性能。
