Magnetohydrodynamic Electrical Power Generation

Book excerpt: 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: A comprehensive introduction to the principles behind the interaction of magnetic field and electric currents with electrically conducting fluids in the conversion of energy. Coverage of all aspects of generator configurations, as well as the disk generator, multi-phase converters, and propulsion systems. Study of the design for AC power generation, covering the control and power conditioning of the generator and the integration of such designs into existing power systems. Study of the use of MHD plant as part of a topping cycle combined with a steam and/or gas turbine or ternary cycle potentially leading to combined cycle efficiencies of up to 60%. Relevant worked examples in each chapter to assist the reader with self-study and the understanding of the topic. This text will appeal to advanced students in power engineering, physics and mechanics. Practising engineers and scientists is the field of power technology will find if an excellent practical reference and a basis for developing ideas on large scale MHD processes. Magnetohydrodynamic Electrical Power Generation forms a part of the Energy Engineering Learning Package. This innovative distance learning package has been established to train power engineers to meet today’s and tomorrow’s challenges in this exciting field. Organised by a team of distinguished, international academics, the modular course is aimed at advanced undergraduate and postgraduate students, as well as power engineers working in industry.
