| Abstract |
This paper presents the concept and implementation of an low frequency power generator using a magnetic nanofluid sloshing phenomena to generate an electro-motive force(emf). Magnetic nanofluids are often applied to power generator because nanofluid have both magnetic properties and mechanical fluidity, and they behave similarly to a soft ferromagnetic material. In addition, magnetic nanofluids have the characteristic that their shape can be freely changed by external force and that they can generate electromotive force even with low frequency or small vibrations. Power generation technology using piezoelectric or thermoelectric elements has limitations in its use because the size of the power is low, at the level of several micro-watts. Here, we developed a model capable of generating power using the flow analysis of magnetic nanofluids and electromagnetic properties based on Faraday's law, and conducted an experimental study. We studied the induced electromotive force characteristics according to the change in magnetic flux density and the amount of magnetic nanofluid using the proposed method, and experimentally verified its validity. |
