摘要：
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 1000MW) designed by the proposed method. The numerical results indicate that the designed FIP MHD generators with the thermal input of 100MW or more are able to be operated with the performance approximately same as the designed one. For the designedMHD generator with the thermal input of 30MW, 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. © 2020 Institute of Electrical Engineers of Japan.
