Experimental and numerical analysis of thermo-magnetic convection in a vertical annular enclosure
چکیده انگلیسی
In the present paper an experimental and numerical analysis of a thermo-magnetic convective flow of paramagnetic fluid in an annular enclosure with a round rod core and a cylindrical outer wall is presented. It is complemented by an experimental analysis of natural convection depending on the inclination angle to show the stability of the present configuration. Convection in an annulus between two vertical co-axial cylinders resulting from gravitational and magnetic environments has been investigated. A strong magnetic field can be an alternative to heat transfer enhancement. The effect of the magnetic field on the convection of the paramagnetic fluid in the annular vessel in various positions was compared. The numerical analysis was done based on the continuity, momentum and energy equations. A term related to the magnetic buoyancy force was added to the momentum equation. The distributions of Nusselt number present minima in two positions of the enclosure, which depends on the reciprocal relationship between the gravitational and magnetising forces.
