Abstract

To fully and clearly understand the development status and key research problems of the seed plasma disk magnetohydrodynamic (MHD) generator, this study reviews the development process of the seed plasma disk MHD generator. The development of the disk MHD generator has experienced the stages of suppressing the ionization instability of nonequilibrium plasma, revealing the characteristics of stable nonequilibrium plasma based on the concept of seed full ionization, and proving the high performance of the disk MHD generator. At present, there are attempts to use a small area ratio disk MHD generator to obtain a high entropy efficiency at a high enthalpy extraction rate with cesium added inert gas as the working fluid. Moreover, the research progress is described from two aspects of numerical simulation and experimental research, and the key technologies and problems to be solved and the development prospects of the seed plasma disk MHD generator are analysed. It is shown that the future theoretical research still will be focused on the generation and ionization process of nonequilibrium plasma. The key technology in the future is still aimed to obtain high-quality, uniform and stable non-equilibrium plasma. Therefore, in the future, it is expected to become a high-power static power supply with a compact structure and high-power conversion efficiency. Tables 2, Figs 9, Refs 153.
种子等离子体磁盘磁流体发生器的研究进展
为了全面、清晰地了解种子等离子体磁盘磁流体动力学(MHD)发生器的发展现状和关键研究问题,本研究回顾了种子等离子体磁盘MHD发生器的发展过程。磁盘磁流体动力学发生器的发展经历了抑制非平衡等离子体电离不稳定性的阶段,揭示了基于种子全电离概念的稳定非平衡等离子体的特性,证明了磁盘磁流体力学发生器的高性能。目前,有人试图使用小面积比圆盘MHD发生器,以在添加铯的惰性气体作为工作流体的高焓提取速率下获得高熵效率。此外,从数值模拟和实验研究两个方面介绍了研究进展,分析了种子等离子体磁盘磁流体发生器的关键技术和需要解决的问题以及发展前景。结果表明,未来的理论研究仍将集中在非平衡等离子体的产生和电离过程上。未来的关键技术仍然是获得高质量、均匀、稳定的非平衡等离子体。因此,在未来,它有望成为一种结构紧凑、转换效率高的大功率静态电源。表2,图9,参考文献153。
