Optimization of NdFeB Magnet Arrays for Improvement of Lorentz Force Velocimetry

This paper presents the design and optimization process of magnet systems for the application in so called “Lorentz Force Velocimetry”. Here weight limitations, physical principle and systematical specifications give rise to a complete new combination of restrictions for the magnetic system design. Beneath the Lorentz force velocimetry background, the paper presents the idea using halbach arrays in combination with cladding technique to improve the currently used magnet systems significant. The magnet systems are geometrically optimized onto the physical principle using finite element simulations. These optimizations are presented on a state of the art reference design for Lorentz force velocimetry in electrolytic flows.
