Abstract
The present paper presents an experimental and numerical analysis of a thermo-magnetic convective flow of paramagnetic fluid in a concentric annuli under a strong magnetic field gradient. The inner cylindrical surface was heated and the outer cylindrical surface was cooled. The applied superconducting magnet was able to achieve 10 T of magnetic induction. A 50% volume aqueous solution of glycerol with a 0.3-mol/(kg of solution) concentration of gadolinium nitrate hexahydrate (Gd(NO3)3•6H2O) was used as the working fluid. The density, kinematic viscosity, mass magnetic susceptibility, specific heat, thermal diffusivity, and thermal expansion coefficient were all measured experimentally. The others, like dynamic viscosity, magnetic susceptibility, thermal conductivity, and Prandtl number were calculated from previous properties. The mass magnetic susceptibility of the fluid was measured with the magnetic susceptibility balance. Convection resulting from gravitational and magnetic environments has been investigated. The numerical results for zero gravity has been also presented. The results show that magnetising force affects the heat transfer rate and that a strong magnetic field can control the magnetic convection of a paramagnetic fluid in a concentric annuli.
