On Synthesis and Characterization of Water Based Cu9Al4-Nanofluid
Nanosized particles of Cu9Al4 intermetallic phase, which is hard (HV 403) and can thus be easily reduced to sizes as low as 20–90 nm, have been synthesized by mechanical alloying of elemental powder blend of Cu and Al. It is then evenly dispersed in water to produce the nanofluids. Thermal conductivity of the nanofluids measured by the conventional transient hot-wire method shows significant enhancement compared to that of water. The enhancement increases linearly with low volume fraction loading of nanoparticles. The experimental data on thermal conductivity of the present nanofluid manifests reasonable agreement with the theoretical predictions.
