Flow in plasma engines are normally described by the coupled equations of Navier-Stokes and Maxwell's, together referred as Magneto Hydro Dynamic(MHD) equations. Such MHD equations, may require complicated boundary inputs and time consuming numerical methodologies for a proper solution. In this paper, it is shown that an equivalent electrical circuit equation approach simplifies the numerical computations of the solution. The plasma engine along its length is sliced into a number of equivalent DC series motor configurations. The parameters of this sliced engine equivalent electrical circuit are derived from the basic MHD equations. Performance characteristics of the plasma engine can then be obtained. This methodology can also be useful for developing a transient approach model.
