Discussions of Closed Cycle MHD Generator with High Enthalpy Extraction Ratio

Abstract

Disk type CCMHD generator with high enthalpy extraction ratio has been discussed from experiments and numerical simulations. The pressure and heat losses of the fluid are found to reduce the output power for the high load resistances. It is also found that the wrong inlet plasma condition affects on the plasma to present the instabilities in the inlet region and results in the reduction of output power. The generator with high enthalpy extraction ratio should match with the load resistance under the situation where the working gas properties change with the power generations. The simulations can interprete the power generation experiments with the FUJI-1 and the shock tunnel facilities.
