Validation and performance analysis for the quasi-one-dimensional models of MHD flows

For the Purpose of quick analysis for the magnetohydrodynamic (MHD) flow, quasi-one-dimensional models for the MHD equipments have been deduced using the turbojet engine model, the variable cross-section pipe flow theory and the expressions of modified polytropic efficiencies. The feasibility of the quasi-one-dimensional models have been validated with the 2D numerical method. Then, the performance analysis has been performed with these quasi-one-dimensional models, which shows that the modified polytropic efficiencies make the models improved, and when the load factors is kept to be constant, the efficiencies of the MHD flow increase by decreasing the average Mach number.
