Available in PDF, EPUB and Kindle. Book excerpt: Liquid metal-cooled fission reactors are both moderated and cooled by a liquid metal solution. These reactors are typically very compact and they can be used in regular electric power production, for naval and space propulsion systems or in fission surface power systems for planetary exploration. The coupling between the electromagnetics and thermo-fluid mechanical phenomena observed in liquid metal thermo-magnetic systems for nuclear and space applications gives rise to complex engineering magnetohydrodynamics and numerical problems. It is known that electromagnetic pumps have a number of advantages over rotating mechanisms: absence of moving parts, low noise and vibration level, simplicity of flow rate regulation, easy maintenance and so on. However, while developing annular linear induction pumps, we are faced with a significant problem of magnetohydrodynamic instability arising in the device. The complex flow behavior in this type of devices includes a time-varying Lorentz force and pressure pulsation due to the time-varying electromagnetic fields and the induced convective currents that originates from the liquid metal flow, leading to instability problems along the device geometry. The determinations of the geometry and electrical configuration of liquid metal thermo-magnetic devices give rise to a complex inverse magnetohydrodynamic field problem were techniques for global optimization should be used, magnetohydrodynamics instabilities understood -or quantified- and multiphysics models developed and analyzed. Lastly, we present a project overview as well as a few computational models developed to study liquid metal annular linear induction pumps using first principles and the a few results of our multi-physics analysis.

This book was released on 2020 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid metals have gained renewed interest as an efficient energy carrier for applications ranging in concentrated solar, nuclear fission, and other industrial processes. Specifically, the nuclear sector is interested in using sodium metal as a reactor coolant for it's a high thermal conductivity and boiling point. While the advantages are significant, there is a need for the development of improved thermal hydraulic components like pumps. Typically, mechanical pumps have filled this role for liquid metal systems. However, there are challenges in their application to sodium systems which cause safety concerns. As an alternative, liquid metals can be pumped using the Electromagnetic Induction Pump (EMIP). Compared to conventional mechanical pumps, EMIPs simplify design by avoiding direct contact of pump components with sodium and by eliminating high speed impellers, seals, and bearings. They also simplify plant design and safety by using unobstructed, low pressure drop, hermetically sealed flow conduits made of compatible materials. Therefore, these pumps significantly improve simplicity and safety which are driving factors in the nuclear fission industry. However, typical EMIP efficiencies are low, ranging up to 45% in the case of the Annular Linear Induction Pump (ALIP). Some of these inefficiencies are due to Joule losses in the pump conduit and fluid. But other inefficiencies arise from finite dimensional edge effects like the Finite Length Effect and the Finite Width Effect. In this work, finite dimensional edge effects of a small-scale ALIP and Permanent Magnet Induction Pumps (PMIPs) are studied through pressure-flowrate and efficiency measurements. Under the ALIP work, theoretical analysis showed that that the Finite Length Effect significantly impacts the total pump performance. Suppression of the Finite Length Effect by magnetic field tapering through methods of 'Coil Shifting' and 'Coil Grading' were experimentally tested and were found to marginally impact the total ALIP performance. Under the PMIP work, theoretical analysis showed that the Finite Width Effect significantly impacts the total pump performance. Pressure-flowrate and efficiency were experimentally characterized for a 12-pole Double-Array Disc-Type PMIP. For the specific PMIP studied, these performance measurements validated a theoretical correction coefficient which accounts for the finite channel and magnet dimensions.

Available in PDF, EPUB and Kindle. Book excerpt: Introduces the reader to engineering magnetohydrodynamics applications and presents a comprehensive guide of how to approach different problems found in this multidisciplinary field. An introduction to engineering magnetohydrodynamics, this brief focuses heavily on the design of thermo-magnetic systems for liquid metals, with emphasis on the design of electromagnetic annular linear induction pumps for space nuclear reactors. Alloy systems that are liquid at room temperature have a high degree of thermal conductivity far superior to ordinary non-metallic liquids. This results in their use for specific heat conducting and dissipation applications. For example, liquid metal-cooled reactors are typically very compact and can be used in space propulsion systems and in fission reactors for planetary exploration. Computer aided engineering (CAE), computational physics and mathematical methods are introduced, as well as manufacturing and testing procedures. An overview on space nuclear systems is also included. This brief is an invaluable tool for design engineers and applied physicists as well as to graduate students in nuclear and mechanical engineering or in applied physics.
