Flow of Electro-Conductive Gas with Constant Speed in the Duct of a Magnetohydrodynamic Generator

摘要

Using a one-dimensional formulation of the problem, an analysis is conducted of conditions of flow in the duct of a magnetohydrodynamic (MHD) generator during condition of constancy of speed which takes into account factors influencing change of electrical efficiency and induction of magnetic field on its length. Special attention is given to selection of parameters by which it is expedient to compare various types of generators, and by analysis of influence of conditions of operation of MHD-generator on its internal efficiency. It is shown that the internal efficiency of a generator is determined by value of local electrical efficiency, and consequently, for a MHD-installation the kind of electric efficiency at which the generator operates is important.
