在完全电离种子的概念下，对使用氩、氦和氩氦混合物的闭合循环圆盘磁流体发电机的性能进行了比较研究。计算表明，纯氩或纯氦是理想的惰性气体在封闭循环磁流体发电机相比，氩和氦的混合物和一个典型的磁流体通道的氦变得紧凑。在典型的盘式发生器中，发现可以建立具有高效率的部分负载操作，并且对于使用氩气和氦气作为惰性气体的盘式发生器，种子分数的波动分别允许在约±3%和±6%的范围内。此外，它示出了一个稳定的等离子体可以保持在很宽的气体温度范围内，通过调整种子分数。
Comparative studies of the performance of closed cycle disk MHD generators using argon, helium and an argon-helium mixture are performed under the concept of fully ionized seed. Calculations show that either pure argon or pure helium is desirable as an inert gas in closed cycle MHD generators compared to the mixture of argon and helium and that a typical MHD channel for helium becomes compact. In typical disk generators, it is found that partial load operation with high efficiency can be established, and that fluctuations of the seed fraction are permitted within the limits of about ±3% and ±6% for the disk generator using argon and helium as inert gases, respectively. Furthermore, it is shown that a stable plasma can be maintained for a wide range of gas temperature by adjusting the seed fraction.
