Some Contributions to Optimization of Faraday MHD Generator Duct

Abstract

For the purpose of contributing to the optimum design of the Faraday MHD generator duct, the authors derive a numerical calculation from the basic quasi onedimensional MHD equations of the diverging rectangular duct and the integrals which express duct size, viz. length, surface area or volume. The calculation is intended to minimize the integrals under the condition of extracting a required output power from the duct, when the applied magnetic flux density, the mass flow rate and the duct inlet or outlet total pressure and temperature of the working gas are held constant.
