“…In our previous experiments, we have shown that it is possible to synthesize alloy nanoparticles of close melting point metals by simultaneously evaporating the metals to form vapors and then rapidly cooling the vapors into a metastable solid state phase [10]. The same idea has been used in this study to synthesize NiFe 2 O 4 nanoparticles.…”

“…10,11) Other researchers have observed anomalous thermal conductivity improvement for dilute suspensions of metallic nanoparticles. [12][13][14][15] After Eastman et al 14) and Jana et al 13) reported the aforementioned results, Ceylan et al 15) have measured a thermal conductivity enhancement of 33% for a 0.006% volume fraction concentration of Ag-Cu alloy nanoparticles in pump oil. However, others have reported no anomalous improvement in similar systems.…”

Nanofluids, a mixture of nanoparticles and fluids, have exceptional potential to improve their effective thermal conductivity and thermal diffusivity, aluminum and aluminum oxide nanofluids with five different volume fractions of nanoparticle suspensions in different base fluids, i.e., distilled water, ethylene glycol (EG), and ethanol were prepared by mixing nanopowder and base fluids. Sonication with high-powered pulses was used to ensure the dispersion of nanoparticles in good uniformity in the base fluids. The hot wire-laser beam displacement technique was used to measure thermal conductivity and thermal diffusivity of the prepared nanofluids. The effects of the volume fraction concentration and particle materials on the thermal conductivity and thermal diffusivity of nanofluids were determined. The results showed that the thermal conductivity and thermal diffusivity increased linearly with increasing volume fraction concentration of nanoparticles in the respective base fluids. In addition, the thermal conductivity and thermal diffusivity increased faster in the Al 2 O 3 nanofluids than in all the three base fluids.

This work reviews experimental data and models for the thermal conductivity of nanoparticle suspensions and examines the effect of the properties of the two phases on the effective thermal conductivity of the heterogeneous system. A model is presented for the effective thermal conductivity of nanofluids that takes into account the temperature dependence of the thermal conductivities of the individual phases, as well as the size dependence of the thermal conductivity of the dispersed phase. We demonstrate that this model can be used to calculate the thermal conductivity of nanofluids over a wide range of particle sizes, particle volume fractions, and temperatures. The model can also be used to validate experimental thermal conductivity data for nanofluids containing semiconductor or insulator particles and confirm the size dependence of the thermal conductivity of nanoparticles.
