Abstract
This paper deals with the study of the analytical model of an inductive MHD generator. In the proposed inductive generator the plasma is produced by means of a periodical non-equilibrium ionization, and an external electrical field segregates the charge carriers contained in the plasma, obtaining two electrically unbalanced flows. The time variation of the charge density makes the ions current time-dependent, allowing the power transmission by magnetic induction, rather than by electrical contact. In this work, a mono-dimensional Simulink model is described with the aim to perform a preliminary dimensioning of this generator. It is shown that the simulations are in good agreement with the expected behavior of the generator and the proposed generation system could be effective for industrial applications.
