Abstract :
The effects of externally induced small fluctuations in the input thermal energy and/or the seed fraction are examined using numerical simulations based on two-temperature MHD (magnetohydrodynamic) equation system. A quasi-one-dimensional approach is adopted for a disk generator. A generator with a high enthalpy extraction rate is considered, and its design parameters are set so that the full ionization of seed contained in the plasma is realized. The fluctuations in seed fraction and gas pressure influence the performance of a generator in several different ways
