Abstract
Experimental investigation was conducted to get insight into convective heat transfer features of the aqueous magnetic fluid flow past a heated fine wire under the influence of an external magnetic field. The local convective heat transfer coefficient of the aqueous magnetic fluid flow around the heated wire was measured in both the uniform magnetic field and the magnetic field gradient. The effects of the external magnetic field strength and its orientation on the thermal behaviors of the magnetic fluids were analyzed. The experimental results show that the external magnetic field is a vital factor that affects the convective heat transfer performances of the magnetic fluids, and the control of heat transfer processes of a magnetic fluid flow can be possible by applying an external magnetic field.
