Abstract
This paper analyses mathematical models and numerical simulation results for a notional miniature, planar, spiral transformer
(MPST) fabricated in MEMS technology, for galvanic separation, proposed to equip an electric harvesting device (EHD). Two
types of core – ferrite and (partially) magnetic nanofluid – are considered. We found that magnetization body forces occur in the
super-paramagnetic nanofluid core and they result in complex, steady state flows consisting of fully 3D recirculation cells.
