要約(英語): The effects of the generator shape and operating conditions on the power generating characteristics and the pre-ionization power in a seed-free pre-ionized inert gas plasma disk shaped MHD generator are examined by two-dimensional numerical simulation. The reduction of the area ratio of the generator outlet to the throat leads the high ratio of the isentropic efficiency to the enthalpy extraction ratio, and a high magnetic flux density and low inlet total pressure provide high enthalpy extraction ratio and the isentropic efficiency, as well as in the seeded plasma MHD generator. Then, the externally applied power for the pre-ionization of inert gas at the generator inlet is found to be reduced owing to the power generation with high electrical efficiency and low electrical conductivity.
