Title: Thermo-Electro-Magnetic Convection in Electrically Conductive Ferrofluids Keywords: Electric and magnetic fields, Electrically conductive, Electromagnetic fluid dynamics, Gravity gradients, Magnetic convection, Multi-physics, Thermal field, Thermal modelAbstract: This work examines the thermo-electro-magnetic convection effect in ferrofluid cooling in presence of alternating electric and magnetic fields. We develop a multiphysics field model for electrically conductive ferrofluid transport and heating calculations under outer electromagnetic and thermal field sources. The finite element method is used for 3D electromagnetic-fluid dynamics-thermal model of high reluctance circular coil. Modeled ferrofluid convection is influenced by magnetic, electric, thermal and gravity gradients References - Mateev, V., Terzova, A., Marinova, I., 2014, Design analysis of electromagnetic actuator with ferrofluid, Bourgas; Bulgaria, 29-31 May 2014, <18th International Symposium on Electrical Apparatus and Technologies, SIELA 2014 - Proceedings, art. no. 687187>, IEEE
