考虑到稀有气体的电离，从理论上和实验上研究了完全电离种子状态下非平衡磁流体等离子体的稳定性。结果表明，通过将种子分数降低到 10~ 5，在实际 MHD 发生器中可以实现放电电流和相应的电场，从而实现种子的完全电离。实验数据表明，在完全电离种子的状态下，等离子体是稳定的，与理论预测一致。获得了高达6的有效霍尔参数，而有效电导率保持在层流电导率的值。讨论了这种稳定方法在实际 MHD 发电机中的应用。
The stability of nonequilibriu m MHD plasmas in the regime of fully ionized seed, taking into account the ionization of the noble gas, is studied theoretically and experimentally. It is shown that the complete ionization of the seed is attainable with the discharge current and the corresponding electric field able to be achieved in actual MHD generators by reducing the seed fraction down to 10~ 5. The experimental data show that in the regime of fully ionized seed the plasma is stable in agreement with the theoretical predictions. Effective Hall parameters as high as 6 were obtained, while the effective conductivity remained at the value of the laminar conductivity. The application of this stabilization method to actual MHD generators is discussed.
