Magnetic Field Effect on Thermal, Dielectric, and Viscous Properties of a Transformer Oil-Based Magnetic Nanofluid

Abstract: Progress in electrical engineering puts a greater demand on the cooling and insulating properties of liquid media, such as transformer oils. To enhance their performance, researchers develop various nanofluids based on transformer oils. In this study, we focus on novel commercial transformer oil and a magnetic nanofluid containing iron oxide nanoparticles. Three key properties are experimentally investigated in this paper. Thermal conductivity was studied by a transient plane source method dependent on the mag… Show more

“…This Editorial note was dedicated to the 1st International Conference on Nanofluids and the 2 nd European Symposium of Nanofluids (ICNf2019). After a short report about the conference, the successful invited submissions [7][8][9][10][11][12][13][14][15] to this Special Issue of Energies were introduced. We believe that the articles in this special issue, whose main parts were presented during the conference, will contribute significantly to the development of nanofluid science and challenges in heat transfer and energy applications.…”

“…Rajnak et al [10] evaluate the thermophysical properties, such as thermal conductivity, dielectric permittivity and viscosity, of magnetic nanofluid containing iron oxide nanoparticles and commercial oil. The influence of nanoparticle content and magnetic field on these properties is studied, showing in particular an anisotropy effect and a potential application of these nanofluids in power transformers.…”

“…Magneto-Nanofluids (ferrofluids) contain evenly distributed NPs-based fluid which use magnetic NPs to achieve superior dielectric property for transformer oil [8]. Recently, many types of research have been carried out on magneto-NFs that show promising dielectric and thermal properties as transformer oil [9]- [11].…”
