Abstract

The effect of an internal magnetic field on the effective thermal conductivity of ferrofluids has been experimentally studied. The thermal conductivity of a ferrofluid sample with 2% volume fraction was measured at different temperatures. The enhancement to thermal conductivity observed was below reported values in the literature. The temperature dependence of the effective thermal conductivity of ferrofluid in a non-uniform magnetic field was experimentally studied and physically explained. It was found that, in contrast with literature on nanofluid thermal properties, increasing temperature could also have negative effect on the thermal conductivity enhancement of a ferrofluid in a magnetic field.
