Abstract:

By using known relationships of the energy balance for electrons and dependence of the conductivity of a turbulent plasma on the Hall parameter, the authors obtained useful relationships which permit evaluating the maximum parameters of an MHD generator operating on a nonequilibrium plasma. It is shown that with argon having an addition of cesium vapors at an electric load coefficient of 0.8 the maximum pressure in the reactor must not exceed 100 atmospheres absolute, even at the presently practically limiting values of reactor outlet gas temperature approximately 2500 degrees K, magnetic field induction approximately 10 T, and power of a given single MHD generator channel. It is shown that with a reduction in M number from 2.0 to 0.5 the maximum permissible pressure in the reactor is reduced from 70 to approximatley 20 atm abs. With an increase in initial temperature and the other parameters remaining constant, the maximum value of capacity of a single unit is reduced. The article contains four illustrations. Author
