Software for Multiphysics Analysis and Design of Annular Linear Induction Pumps

High-temperature nuclear reactors, and irradiation test-capsules, make use of molten metals and their alloys for heat transfer functions from the active zones due to its high degree of thermal conductivity. Pumping of these liquid media by classical mechanical radial or axial pumps is, however, rather difficult and the lifetime of such devices is relatively low. It is known that electromagnetic pumps have several advantages over mechanical pumps: absence of moving parts, low noise and vibration level, simplicity of flow rate regulation, easy maintenance and so on, making them a logical and very efficient option for molten-salt and liquid-metal reactors. We will develop software for the design, modeling, and simulation of annular linear induction pumps for nuclear applications over a phase I period of 12 months. This research and development effort will complement and advance the job already initiated by this small business concern. The initial evaluation of physical models and validation of computational results will be performed simultaneously through the fabrication and testing of small individual components during the initial Phase I. During the proposed phase II, further development of the software, including the addition of an optimization module, increased GPU and parallel computing capabilities, further experimental validation and its integration to commercially available CAD/CAE software will be performed. Development of an interface for its integration into nuclear simulation packages such as TerraPower’s ARMI and DoE’s MOOSE will also be evaluated for future development. The coupling between the electromagnetics and thermo-fluid mechanical phenomena observed in electromagnetic pumps gives rise to complex engineering and numerical problems observed in different type of applications in the nuclear, space and industrial field. Therefore, future applications of this research can lead to the design, analysis, fabrication and operation of technologies with applicability on: thermal control systems, advanced nuclear propulsion and power systems, generation IV reactors, targetry and machine protection mechanisms on high energy particle accelerators, concentrated solar power plants and biomedical engineering problems such as artificial MHD heart studies.
