CHARACTERISTICS OF FARADAY AND DIAGONAL MHD GENERATORS WITH CRYOGENICMAGNET SYSTEMS

This paper addresses linear magnetohydrodynamic (MHD) generators of th e Faraday and diagonal types with cryogenic saddle-shaped magnet syste ms. Procedures are described for the calculation of the characteristic s of MHD generator on the basis of quasi-one-dimensional analysis of M HD processes in the generator channel with due regard for the dynamics of development of the boundary layer on the channel wall and for the two-dimensional calculation of the stressed-strained state of the wind ing and structural elements of the magnet system in the approximation of the theory of composite shells. The choice and partial optimization of the parameters of MHD channel and magnet system involve the use of methods of nonlinear programming. The results are given of the calcul ation of the outlet parameters, mass and dimensions of MHD generators of the Faraday and diagonal types with cryoconducting magnet system.
