Abstract: Two series of nanofluids were prepared by the researchers, using water as the carrier fluid, and Al2O3 and TiO2 as the nanoparticles; up to 6% particle volume fraction was used. The thermal conductivity and thermal diffusivity of the nanofluids were measured using the transient plane source (TPS) technique, and dynamic viscosity was also measured. The amount of nanoparticle volume fraction affected the value of thermal conductivity, but the nanoparticle cluster size did not have a significant impact. The nanofluids were studied from 1 to 40°C, and it was determined that the Al2O3 nanofluid exhibited more desirable thermal properties than the TiO2 nanofluid.
