The performance and plasma stability in a high-temperature inert gas plasma MHD generator with a high enthalpy extraction ratio have been simulated numerically. To achieve a high enthalpy extraction ratio, various generator channel lengths and magnetic flux density distributions are examined so as to improve the MHD interaction strength and effective electrical conductivity. It is found that an enthalpy extraction ratio of 30% is reachable for high-temperature inert gas plasma MHD generator, and as being similar to an experimental small-scale generator, steady and homogeneous plasma can be realized at a high inlet total temperature even for a high enthalpy extraction generator with long channel length and shaped magnetic flux density distribution.
