Ceramic Foam Filter (CFF) ElectroMagnetic (EM) priming systems with square-shaped solenoidal coils are in the process of full-scale industrialization. The demands on the EM fields used in such a system are substantially different from the requirements in the existing EM pumping systems used for liquid metals. The same fundamental physics are applied, i.e. Lorentz forces induced by time varying EM fields; however, these forces are used to overcome the metal surface energy and force metal into the cold air filled pores of the CFF, instead of simply producing metal movement.
The present study discusses the design methodology for square shaped solenoidal coils applied to EM priming using a combination of analytical models, experimental measurements and FEM simulations with COMSOLŪ Multiphysics. The EM force field required to prime different sets of filter grades at different sizes (4, 9 and 23 inches) is estimated using FEM, and validated against experimental results.
