TLDR
In this article, a steady-state method was used to evaluate the effective thermal conductivity of Al2O3∕distilled water nanofluids with nanoparticle diameters of 36 and 47nm.Abstract:
A steady-state method was used to evaluate the effective thermal conductivity of Al2O3∕distilled water nanofluids with nanoparticle diameters of 36 and 47nm. Tests were conducted over a temperature range of 27–37°C for volume fractions ranging from 0.5% to 6.0%. The thermal conductivity enhancement of the two nanofluids demonstrated a nonlinear relationship with respect to temperature, volume fraction, and nanoparticle size, with increases in the volume fraction, temperature, and particle size all resulting in an increase in the measured enhancement. The most significant finding was the effect that variations in particle size had on the effective thermal conductivity of the Al2O3∕distilled water nanofluids. The largest enhancement difference observed occurred at a temperature of approximately 32°C and at a volume fraction of between 2% and 4%. The experimental results exhibited a peak in the enhancement factor in this range of volume fractions for the temperature range evaluated, which implies that an opt...read more

A review on applications and challenges of nanofluids
TL;DR: It has been found nan ofluids have a much higher and strongly temperature-dependent thermal conductivity at very low particle concentrations than conventional fluids, which can be considered as one of the key parameters for enhanced performances for many of the applications of nanofluids.

TL;DR: The International Nanofluid Property Benchmark Exercise (INPBE) as mentioned in this paper was held in 1998, where the thermal conductivity of identical samples of colloidally stable dispersions of nanoparticles or "nanofluids" was measured by over 30 organizations worldwide, using a variety of experimental approaches, including the transient hot wire method, steady state methods, and optical methods.
