Abstract:
In this thesis, the momentum and heat transfer of a ferrofluid in a partially filled vertical porous channel under the influence of nonuniform magnetic field has been investigated. In this magneto-thermo-echanical problem, our objective was to enhance the heat transfer which is attributable to both ferrofluid and porous medium unique characteristics. Accordingly, this problem is twofold and their relevant aspects would be discussed respectively. The ferrofluid flows upward, in the channel and a gradient magnetic field is generated by a permanent magnet in the vicinity of the channel. To solve the system of govering equations,COMSOL Multiphysics software has been used. The results shows that the special configuration of the magnetic field and controlling the effective parameters can lead to great heat transfer enhancement. With special utilization of the magnetic field, the Nusselt Number value is increased about 70 %, which shows that thermomagneic convection mechanism can enhance heat transfer
