Magnetohydrodynamic Electrical Power Generation
Magnetohydrodynamic Electrical Power Generation Hugo K. Messerle University of Sydney, Australia The global demand for energy continues to grow. Magnetohydrodynamic (MHD) conversion processes offer a highly efficient, clean and direct conversion of energy for power generation and propulsion. By converting the kinetic energy of a flowing fluid into electricity directly, MHD systems help address the problems of environmental pollution. At the same time MHD is particularly suitable for primary energy sources or fuels providing energy at temperatures extending far beyond those manageable by any conventional thermal conversion plant. It therefore offers a potentially more effective utilisation of fossil and nuclear fuels. The author covers all aspects of MHD power generation, including the design and operation of MHD conversion systems in practice. Features include:
